You want an apple but you spend all your time thinking about bananas and how you hate them, how you wouldn’t want to eat one. You tell everyone how much you dislike them.
If you spend half the day thinking about apples and half the day thinking about bananas - you are wasting half your time
The Apple represents something you want. The banana represents something you don’t.
This is the same in life: we waste so much time, energy and money on things we don’t want.
Change happens in the mind.... by training your mind to think about the things you want, not the things you don’t want.
