limitation

Everyone has their limitations. However, i think that limitations can't be an obstacle which holds you on. 1000m swimming looks like so hard to achieve, but i did it too yesterday where i have a bad muscle ache all over my body =.= Anyway, i feel relax after every exercises that i did. Today i have attended a "white coat ceremony" of my seniors and i realized that time passed pretty fast. Remember that day i came to this school and my seniors guided me along in all matters, after few years they are going to the hospitals for clerkship soon. The next year would be my turn, have i ready yet for all this?
