20. See Failure as an Instruction Manual
Failure is illuminating. It reveals every broken board beneath our feet, every crack in the wall, every pothole in the road. Do not shun failure. High-five it. Hug it. Engage in lusty pawing with it. Failure means you’re doing. Everybody fails before they succeed. Failure is how we learn. Failure is part of the grand tradition of figuring out how to be awesome.
Totally correct. About anything, really, but in particular anything having to do with the creative arts. It takes a lot of practice, a lot of experimentation, a lot of try-fail-try-fail-try-fail, and did I mention a lot of practice? to make it up the Creative Arts Mountain. If you can't learn from your mistakes, you'll never make it to the top of that mountain, and if you're afraid of making mistakes, you'll be so paralyzed you'll never make it past the foothills.
Read them all, noting that most of them are delightfully profane. :)
