Which do you think is worse, failing or never trying?

We always worry about failing anything, sometimes fixated on one unhappy event in our lives while forgetting all the other successful times. But should you avoid trying so as not to fail, or to keep trying, regardless of failure? Which do you fear most?

For me, failure is just practice. If I never attempt anything, then I cannot pass or fail it! What we might regard as 'failure' is merely just a temporary obstacle, or detour, to help us achieve our goals. It means we are not quite ready yet, and need more experience. So not even trying would be worse for me, because without trying I cannot test myself to see what I'm capable of.

But how about you?
