Answer by Shulamit Widawsky:
Turns out, your brain cannot really tell the difference between completely imagining something, and actually experiencing it.That means, that if you don't have time to practice throwing baskets into the hoop one day, but you usually practice, you can imagine throwing basket after basket, and your brain will actually improve your skills when you get back to the court.It means, that if you can picture yourself doing something that you are afraid of, you will become less afraid, as if you actually did it for real.It means, that if you keep thinking that you hate doing a certain thing, or that you don't want to do a certain thing, say, washing the windows, you will convince your brain that this is a task to be avoided. But if you imagine wanting to wash the windows, over and over in your mind, by the time you get to those windows, you will actually want to wash them…which actually, you really do, because you are so tired of them being dirty.What you tell your brain, your brain believes.Tell it you are great.Don't tell it you are bad.Imagine the person you want to become, over and over, and you will become it.Imagine the person you don't want to become, over and over, and you will become that.This does not work if what you imagine is a final outcome, without imagining what it takes to get there. For example, imagining yourself wealthy, but not imagining yourself investing or working, will not magically create wealth. You have to have a plan, and imagine carrying out the plan. Same for fame. Same for sex. Same for career.
