I’ve kept saying that failures helps you to learn what went badly, and improve. The philosophy is simple: sometimes you win, sometimes you learn.
I didn’t use or have this philosophy something like 10 years ago. In the past I thought that failure is bad, and should be avoided no matter what. Much of the school teaching concentrates on spotting errors, and then giving penalties if you make any. In exams they don’t count how much you got right, they focus on counting how much you got wrong. That’s a really bad way to look at things.
In the recent years my attitude has changed dramatically on this: there’s no failure, or if there’s “loss” it means chance to learn something. Failure means exactly the opposite. It gives you the opportunity to ask yourself: “what’s good in this situation?”. It gives you chance to learn and improve. Some of the best lessons I’ve learned was because of “failure” or doing mistakes. Failing is good, doing mistakes is good – when you learn from them.
Sometimes you win, sometimes you learn. That’s how it goes.
