School in General and This Semester

I have to keep in perspective that my grades do not measure who I am and the extent of what I have learned. As I complete my final essays, the doubter in me lurks over my shoulders. The dark shadow tells me to stop revising and just turn it in 'cause it (the paper) is what it is. But I keep sitting here rewriting and rewriting trying to make it better. Sometimes I feel like it is like trying to clean up a junk yard. And I can see the finish line, can touch it. Here is where I want to just stop running/writing/thinking/ and sit on the curb. Running out of gas/flat tires/cannot go anymore...But everyone is watching me run this race and waiting for me to fall out...I am breathing so loud.
