Trying is not about winning/getting the right answer, it's about gaining experience. Then you'll become skilled and win/get the right answers more.

So even if I play the piano badly now, if I practise, not being down because my playing is bad, but hoping that the familiarity gained will help me do better. Don't fear getting it wrong.

Then I enjoy it more, and I don't worry so much about trying, because it's still worthwhile even if I don't get it right. That's not what trying it about anyway.
