Make more mistakes! Do something wrong. The worst that could happen is that you would die and ruin everything for everyone forever. But that’s extremely unlikely compared with what will probably happen, which is that you will get better at whatever you were trying.
If you start something new, you’re bound to make mistakes. But let’s imagine that you don’t. Let’s imagine that you ace it every time, right from the get-go. Aside from feeling great about yourself, you would probably find out soon enough that you weren’t really progressing in terms of skill. After a little while, you’d stop feeling so great and try to find out what people who could do it better than you were doing. Then you would realise that you weren’t really acing it every time from the start; rather, you were doing decently, but couldn’t see the flaws in what you were doing. So you decide to study the works of the best. The problem with that approach is that more often than not, you only ever see the best of the best. The best people get into the limelight, and once they’re there, all they do is show off the best things that they have created, and what you don’t see is all the discarded paper, deleted documents and failed attempts that they made in learning, and still make all the time. As a result, it’s easy to get disheartened and feel like your work will never be as good as others who are successful.
The point is that to improve you must learn, and to learn you must make mistakes. The more you put yourself in a situation where you can make some mistakes, where you don’t quite know how to do something, where you have to disengage autopilot mode, the more you’ll find that you discover ways to do things and techniques that you didn’t know about.
