What's wrong with failure?

It is quite true that a person learns better through their failure.

At least that is what i hold.

But why people/i still scare of failing?

1. I rarely fail. Therefore naturally it's scary to go through something not normally occured.
2. Failing = losing and losing sucks
3. There's not that many opportunities for you to screw up.
4. It's a chance to be run over. You missed a chance. You won't catch up with others.

There are probably tons of reasons why people/i are scared.

But i guess it's not a jusifiable excuse for doing nothing.
For not taking risk...
For not moving on...to something new
some new things

I guess it's not.

Or else humanity probably goes nowhere.
