In all areas of your life, career, relationships, health. You don’t have to have a crystal clear picture. But without a vision, it’s difficult to create anything. You’ll just be throwing paint at the wall instead of creating a work of art. See this visual often but don’t tie it to your happiness. It’s there. It’s waiting. But it’s doesn’t determine your happiness today.
While you may give someone the evil eye when they annoy you, people used to take malevolent looks much more seriously. Usually triggered by jealousy, giving someone an evil eye was supposed to cause all manner of suffering including mental illness and physical maladies. For thousands of years, people have been using evil eye talismans, or nazur, to ward off the bad luck caused by these curses.
Expectation is similar to knowing, as described above. Expectation is more general. Someone who lives in expectation of good things happening will attract good luck throughout their life. That doesn’t mean they won’t suffer ‘negative’ events, it simply means they have programed themselves to a positive expectation. When they get it, it feels natural; the normal course of events. Many people do the exactly opposite, they program themselves to expect the worst and are always surprised when the ‘worst’ keeps turning up.

Simply put, the Law of Attraction is the ability to attract into our lives whatever we are focusing on. It is believed that regardless of age, nationality or religious belief, we are all susceptible to the laws which govern the Universe, including the Law of Attraction. It is the Law of Attraction which uses the power of the mind to translate whatever is in our thoughts and materialize them into reality. In basic terms, all thoughts turn into things eventually. If you focus on negative doom and gloom you will remain under that cloud. If you focus on positive thoughts and have goals that you aim to achieve you will find a way to achieve them with massive action.
