Failing is part of success. No one gets it done on the first try, so better get it out of the way so you can learn and move on to the next thing!
It’s not whether you win or lose, fail or succeed, produce a masterpiece or a piece of crap–it’s the doing that matters. To quote a couple more go sayings that I’ve applied to writing:
“Sometimes you win, and sometimes you learn.”
“The master has failed more times than the beginner has even tried. ”
So do it! The only failure that matters is a failure to try in the first place.
