You have to feed your mind full of things you want in life.
It is imperative that you do. The brain is weak when it comes to seeing what doesn’t, or has not existed and it will try to keep you in place just because it doesn’t know what to do with your dream. That is where the feeding comes in it is imagination, it is work and exploration, but if you want to do better, if you want to be better you will have to see it in your mind first.
Your mind will create the behavior in you, you must embrace it, if not it will stop trying and you will be stuck.
Bottom line: Embrace and believe in good things for yourself, see them happening, and do them.
