You’re also competing with other people’s intentions – both good and bad. So, be aware that if your desire is in direct conflict with someone else’s stronger desire, the universe will respond accordingly. The Law of Attraction does not give you full and total control of your life, it simply states that like will attract like. You can use this to your advantage by being intentional with your desires, but this isn’t magic.
It’s difficult to free yourself completely from doubt, fear or feeling as though you don’t deserve something. Your instinct might try to combat those feelings using negative thoughts like, “Don’t be afraid” or even direct conflicts like, “You deserve this.” Unfortunately, such methods are ineffective and simply don’t work because they reinforce negative thoughts and feelings.
Success rate of 0.1%? Where'd you get that statistic? But whatever the actual number, your question is an invalid one. The law of gravity works 100% of the time, except we can fly planes, right? Yes, I know that sounds silly, but it's really to show you how silly YOUR question is because "LoA" works even "negatively" (put in quotations because human perception is what labels things as positive or negative when really, the universe is 'neutral' and things don't happen as a way to punish us... that's just ridiculous, it's not personal).

The main principles of the Law of Attraction can also be discovered in the teachings of many civilizations and religious groups. An example, in the Proverbs 23:7, it reads ‘As a man thinketh in his heart so is he’. Proof of praise for the Laws of Attraction can be uncovered throughout the ages; all recorded and taught in different ways, but still there for all of humanity to find.
