I have always found there is a little tiger inside me when I am on my period, started about the secon cycle of my life. I simply refuse to be a victim of my body and this "I will do it, and I'll work harder and better in spite of it!" just comes out of me. I don't know how to explain that except it's a mindset. I just will NOT let that time of the month slow me down, I will push through anything short of puking or diziness just to prove to myself that I can do it.
