Never trying is WORSE!
Because if you think about it, you could easily try something new and fail at it right away, but failing is what helps you learn! Failing helps you figure out a way to correct the mistake! Because if we never failed at some point in our lives, obviously everything we've done is too easy for us! And there's really nothing fun about something being way too easy for us!
Think of this as a video game. If you fail at a certain level a lot of times, that's okay, because as you figure out more and more ways to edit what you're doing wrong, you might just beat that level!
But if you never try to beat that level, then when you invite a friend over to play the same game and you're hopelessly failing to pass that level, you'll be embarrassed!
If you never try, you'll never know. But if you fail, at least you'll have some strength to overcome your past mistakes!
Bottom Line: If you don't try, you'll fail automatically. But if you try and fail, you'll eventually learn to get good at it if you keep at it.
