Hurry up and fail fast.
Few things are as important as our failures. The cliché of us learning when we make mistakes is a cliché for a reason: it’s inconveniently true. Not making mistakes might teach you something as well.
Making mistakes teaches you what not to do, or what not to pursue. Not making mistakes shows you one way that gets you to the destination you want to go to.
What not making a mistake doesn’t teach you is where your limit is. When you make a mistake, you know that you’ve reached some kind of limit, and that limit makes you fail.
Sometimes that limit is focus or concentration. Sometimes it’s your physical ability or your knowledge of a matter.
Regardless of what the limit is, then you make a mistake, you learn where that limit is. And that’s where you develop as a human being.
The mathematician doesn’t develop new theories when always getting the right answer. The boxer doesn’t develop from always knowing where the next punch is going to be thrown.
The point is, to develop you need to hurry up and fail fast. Because where you fail, is where you’ll discover new grounds.
