Failing at something is never bad.

I really believe that failing at something is the only way of learning something truly new. As long as you can weather some tough times with relentless optimism, there is never a bad time to throw yourself in at the deep end and take some risks. You might fail - in fact there will certainly be things that don't work as you expect - but the more you expose yourself to risk... the more you'll reap in return. There is never a good time to do something different. So you might as well do it now.
