The way to look at this is not what happened in the past but what you learned from it for the future.  Unfortunately the world is not a fair place and the work environment is even more unfair - especially where women are concerned. 

There have been times when I was subjected to unfair treatment in the work place but, believe it or not, I did learn from each of those experiences.  And while they were unpleasant (and even hurtful) at the time, I truly believe they are part of what has made me the woman I am today.

So take a quiet moment to reflect on your experience and decide if you were in that position again, what would you do differently.
