> at least occasionally one should choose to do something one will regret. Negative experience is crucial for learning, unfortunately. "If you never fail you don't try hard enough", etc. This is trivially understood in physical training: you have to get yourself exhausted to become stronger.

I do not necessarily support or reject this view, I'm just trying to clarify the point.
