Screwing up is one of the best ways to learn. It’s a simple as that. Kids do it all the time, but somewhere along the line, we end up being scared of making mistakes. Of “failing”.
First of all, making a mistake is not failing. Making the same mistake over and over could be considered failing, but making one and learning from it is considered getting smarter.
Also, preparing yourself for the inevitable mistake, will no doubt help you cope with it. Visualization can help you out here.
Learning to let it slip when you make a mistake is as hard as forming any other habit, but it’s one that’ll be of enormous benefit to you.
The point is not, to not care whether you screw up or not, the point is that mistakes do happen – sometimes because of external factors, sometimes because of internal factors. As Rocky said “it’s not about how hard you can hit, it’s about how hard you can get hit and keep moving forward”.
Personally I’m always learning, and always making mistakes. Don’t be afraid of either.
