I have always heard that line "Fake it till you make it" and have thought of it as just kind of a way to short circuit reality and that whole law of attraction kind of stuff.
Pretend You Are the Best - Fake It
I decided a few weeks ago that I would go out and pretend that I was the best defensive player in the league, I have nothing to lose thinking that, of course I am not cocky at all so I just grind away, and in fact I played my best hockey ever.
I once heard, and I am sure it is true, that if you visualize shooting basketball free throws for an hour it will give your body the correct muscle control from the brain to the arms to be almost equivalent to shooting those free throws. Our brain so often knows exactly what to do but we are nervous that we can't do what is important, we hold back when we really do have the ability.
So next time that you are hoping or trying to push yourself, trying to perfect a new skill, trust in your skills that you have. Fake it till you make it, fully expect that you can do that new thing and see if it works out for you. I suspect that it will.
