A change of heart or finding the address of my dreams?

I always wanted to find cures to diseases for which no cure existed. With that desire, I went into graduate school to become a scientist and endured all that is endured: the long days, nights and weekends in the lab, doing experiments that added just one little piece to the puzzle of science; the frustration of failed experiments and low budgets; the work with thousands of mice (I actually counted over 3000 mice sacrificed over my graduate school career). But I was happy because I was on the road to becoming a scientist and finding a vaccine for Human Immunodeficiency Virus (HIV).
