There’s a difference between cultivating failure and cultivating willingness to fail in the pursuit of success. Many people are too scared of failing (or of being perceived to have failed) to actually try anything that’s not 100% safe.
Sure all I’m saying is there’s a difference between saying that it’s hard to convince people of this good advice if they don’t have the benefit of experience and we shouldn’t force them to follow it if they don’t believe it, versus we shouldn’t try to give people this advice because it may deprive them of the opportunity to fail.
