I think I overused exactly. But, imo, you should do that in one point. Only then you can learn from mistakes, and learning from mistakes is the best learning.

I think I overused exactly. But, imo, you should do that in one point. Only then you can learn from mistakes, and learning from mistakes is the best learning. At least for me. Same in real life. Many examples, here's one: I'm confident and careful with ultrasharp cutting tools. But only because I cut myself bad a couple of times: before that I was more reckless even though I thought I was doing ok. Also others telling me to be careful had no effect whatsoever.
