I'm in the same pool as you guys. I keep trying too hard to make it as unique as possible, yet it's hard. In my composition classes, I always knew what I wanted to write about. Yet, now where it counts the most, I have a block. For someone who's outspoken, I have can't get a good lead. I ripped my first drafts and am thinking of starting from scratch.
I have a few leads- when I was 16 my friend lost her finger in a freakish accident and I remember going with her to the er and standing by her. That really got me thinking about medicine (I knew I was interested before though).
I spend two months a year with my grandfather who suffers from various diseases. I help him with his medicine, get dressed, and I'm there emotionally for him.
While I volunteer in a cancer hospital, I remember speaking to a family member of a patient going into surgery and I was saying it must have been a long time in the waiting room, then he replied "I have the easy part." Till this day I remember that quote and use it in my life.
So, I didn't want to use these b/c they're cliche..or am I wrong? They are very sincere to me, but I don't know if I'd be able to convey that well, since I'm a little inhibited when talking about my emotions.
Good luck everyone! I know I think about my PS constantly.
