Unfortunately you can't tell
any of these things to someone younger because they probably think they already have it figured out and they don't need your help. (Gott knows I did.) From the article:
"I don’t buy the romantic notion that my life has been somehow richer or more interesting because of all the times I screwed up; nor that the mistakes were “put” there to help me learn. I made them myself—through ignorance, fear, and a dumb wish to have everyone like me—and life and work would have been less stressful and more enjoyable (and certainly more successful) without them. So here are some of the things I wish I had learned long ago."
