I don't know if proud is the right word, but I am somebody who does not, on the whole, have the highest regard for my own stuff in that when I look all I get to see are the flaws.
Depending on what your interest in theater is, I always recommend working on plays. It's a great way to be introduced to the field, and also a great way to be seen by agents and representation. I'm also a great advocate for studying acting at a drama school or a college.
