The author demystified luck as something random and breakdown several conditions in attracting luck with ample examples. His style of language can take some efforts to understand but it's worth a read as one may understand why he is not inclined not rub shoulders with luck in the past but this would change if the principles from the book is applied.
"Simply focusing on finding Mr. or Ms. Right isn’t going to get you there, but it is definitely going to help your process if you use other techniques as well! For instance, if you focus on manifesting your happy romantic destiny while creating a strong dating profile and figuring out your goals and deal breakers, you’re more likely to be successful than if you have a negative attitude while doing this important work towards dating smart. ... As with anything else, manifesting your destiny doesn’t happen with a magic wand. Very little in life happens with a single act — but having a positive outlook and focusing on your goal is going to move your success along, in the right direction, that much more quickly. It will also help overcome obstacles that might trip you up with a less focused and positive outlook," according to Masini.

Many people turn to a greater power to help them increase their luck. Some say a prayer before they start to enter sweepstakes, asking God to help them win what they need or to help the prize go to the person who needs it most. Others feel that asking God for specific prizes is inappropriate but ask instead for the strength and the positive attitude they need not give up and to keep entering sweepstakes.
Many people have limiting beliefs which keep them from allowing abundance and happiness into their lives. If this describes you, realize that you must first change your limiting beliefs into thoughts that you are deserving, worthy, lovable, desirable, and capable—as well as smart enough, strong enough, attractive enough, rich enough, good enough, and “enough” in every other way that matters to you.
wallace wattles is not god. just because a teacher of a subject says something dumb like don't help the poor ever doesn't mean the whole subject they teach is worthless. but it's true that if you surround yourself with low achieving struggling people it will effect you differently than the opposite and if you think about illness and victimhood most of the time it will effect you differently than health and power

The New Thought movement (Law of Attraction Origins) grew out of the teachings of Phineas Quimby in the early 19th century. Early in his life, Quimby was diagnosed with tuberculosis. Unfortunately, medicinal treatment wasn't working, so he began carriage riding through his hometown, Lebanon, New Hampshire. He then regained his health and recovered, an event that prompted his study of "mind over body".[10] Although he never used the words 'Law of Attraction', he explained this in a statement that captured the concept in the field of health:
Under laboratory conditions, cutting edge science has confirmed that every thought is made up of energy and has its own unique frequency. And when this energy and frequency of a single thought radiates out into the Universe, it naturally interacts with the material world. Of course, it has long been known that matter, or physical objects, are also just packets of energy at the sub-microscopic, quantum level. And so, as your thought radiates out, it attracts the energy and frequencies of like thoughts, like objects, and even like people, and draws those things back to you.
Be sure about what you want and when you do decide please don't doubt yourself. Remember that you're sending a request to the Universe which is created by thoughts and therefore responds to thoughts. Know exactly what it is that you want. If you're not clear/sure, the Universe will get an unclear frequency and will send you unwanted results. So be sure it is something you have strong enthusiasm for.
There's an old saying, perhaps you've heard it, "consider the source"? Do you not see the irony in your criticism of LOA, classifying it as a "pseudoscience", with your employer being PSYCHOLOGY TODAY? if I'm not mistaken, has the field of psychology itself, in It's infancy as well as today, not been debunked, by "actual science", referring to it also as "pseudoscience"?
Show up and always be prepared. Have you ever noticed that the luckiest people at work seem to be the ones who show up prepared for meetings? They plan projects and develop timelines. They work well with other people and they always seem to have loads of energy. They are optimistic and confident because they are prepared. If you want to be one of the lucky ones at work who gets a promotion or a regular pay increase, do your homework. It’s no accident that the more prepared you are to tackle a challenge, the luckier you’ll be at successfully reaching your goals.

You may not have discovered your passion or your life’s work yet. Unless you attempt new things, you may never discover what that is. Keep an open mind to all possibilities. You don’t know if you could be an talented ceramicist unless you pick up a lump of clay and give it a go. How do you know that you aren't a gifted energy healer? Or an amazing tarot reader? No-one ever said, on their death-bed, “Gosh, I wish I hadn’t done all those things.” People who broaden their minds and their life experience become interesting characters who attract good luck and good friends.
Your second point is an interesting discussion. You are correct that in its infancy, psychology was criticized for claiming to be a scientific field and not living up to that assertion by performing quality research. I believe that this question has been put to rest as the rigors of publishing in psychology require randomized, double-blind, placebo controlled trials.

Creative visualization is a cornerstone of using the Law of Attraction, and meditative exercises are part of this process. For example, you are encouraged to spend 10-15 minutes a day on building an increasingly detailed image of the life you want to develop. However, visualization actually extends far beyond these mental pictures, and can be practiced in concrete ways every day. For example, you will learn writing exercises here on our site and artistic approaches that focus on externalizing your goals and making them more real. You can be as creative in your visualization process as you like, and trying out the basic skills may inspire you to come up with unique methods that are even more effective.

Things happen faster when you let go and be patient. If you keep worrying about it, you are thinking about lack. if you let go of it, there's no resistance. What's there to block you? I like the example of gravity that Supernova gave us about the plane notion. we can still fly planes despite gravity. Otherwise without gravity we would keep ascending into the depths of space! The same way, you can attract nothing despite LoA actually attracting it for you.. Adding to this, there is still the force of gravity acting on the plane but the net resultant force is upwards. The same way, you think the law of attraction won't work for you but in fact it's the law of attraction giving you the stuff that is needed in order to change your mindset that it will not work for you and hence go to the default issue that many people have. You have the thought that it doesn't work for you. However, if you change that mindsetby looking for proof that it does, you will see that the law of attraction helps you MUCH MUCH MORE.
Change your strategy: It may occasionally be necessary to change the way we see things and the way we act in order to “get lucky.” Surely you know many people who, no matter how hard they try, cannot seem to change their destiny. It’s not about good or bad luck, but about knowing how to behave properly and knowing the exact moment in which to change course or direction. Instead of accumulating failures, innovate.

Before you begin to embark on the incredible journey towards true enlightenment in the Law of Attraction, it is important that you understand that you can apply it to your life and it can be effective if the correct tools are used. The practices and beliefs in this law have been igniting the lives of great individuals throughout the course of history.
