Question

The main point of the power process: risk being a fool, is that mastery in most activities calls for the willingness to do something new, to fail, to make corrections, to fail again.

Answer 1

I believe the answer is: True

When we do something foolish and risky, we would put ourselves in a situation where we have to quickly adapt to new things if we want to survive.
Even though sometimes this ended up in failure, it also give us a lot of experiences that would help us in our future decision making.
