Try not. Do... or do not. There is no "try."

My almost-three-year-old started to climb the rock wall on the big-kid playground at Becker the other day.  Being a moderately overprotective father, my impulse was to go over and help her down so she didn't get hurt.  Instead of grabbing her, I stood by, ready to catch her in case she fell. "Daddy, help."
"You got up there sweetie, you can get down."
She growled at me for a second, but then started looking for other handholds. When she didn't see a way down, she started to go up instead.  Seconds later she slipped and I caught her.
"Dat was scary."
"You okay?"
"Put me back, please," she pointed up to the wall.  We started again from the bottom, and after five or six more falls/fails, she eventually made it to the landing.


What you have chosen to do is weird and a little bit scary.  You could get all kinds of help from your guides, but that would be too easy.  And it's not because we're mean (well, not most of us anyway).
We know why it's better for you to fail.
When we fail at anything, it kind of sucks. Kind of. But we remember it,  learn from our mistakes, and get better next time.  Trying doesn't matter. Getting it wrong (or right) and knowing why that happened is the key to learning.  First Attempt Is Learning.  If you're scared of failing, you need to ask yourself: are you really that scared of learning?  What's the worst that could happen?

So go mess something up!
