I learn how to do things by doing that thing.
I get frustrated when people say “I want to do this” or “I’m going to learn how to do this” (usually followed by inaction). Often as people we have a tendency to think that by talking about doing something we’ll mystically gain these abilities or talk ourselves into a position where we are suddenly doing these things.
Things just don’t happen like that in my experience. Head down, crack on, go through hell learning how to do something. Make mistakes, make more. Break the thing you were working on. Fix the thing you were working on. It might take a longer road to get there but by the second time it feels less difficult than the first. By the third time you roughly know what you are doing. Expertise is born here and developed with further repetition.
The most important thing is to do it. Because even if, in the end, I hate the finished product the things I learn along the way are so much more valuable for the road ahead of me.
