Don't Mess Up (Or Keep Trying Until You Succeed)

There are many awesome things about being a woman in a field dominated by men, but one of the less awesome things is the fear of having your failures held against not just yourself but all women.  Piled Higher and Deeper has a great take on this from the perspective of the woman and xkcd takes it on from the perspective of (some) men:

So obviously, the solution if you are a woman is never to make a mistake.  But let's be honest, you will.  Making mistakes is an important part of learning.  When you make that inevitable mistake or two or ten, it's tempting to give up and walk away.  Don't do it.  If you do, you don't have the opportunity to show everyone that you can get it right.  They'll only be able to remember you for the failure and not the triumph.
