I think that there is a confusion here: making mistakes is not a necessity for success. Making mistakes is necessary for learning, but not for success. Any lottery winner can confirm that.<p>It is all down to this philosophy that says that success comes from hard work and recovering from failure, and that if you try hard enough you eventually reach your goals. But you also need sheer luck.<p>And please, don't translate luck as "being at the right place at the right time" because that amounts to trying hard enough, but is not. You can be at the right place at the right time because of... sheer luck.
