You have a rare opportunity in comedy to celebrate yourself. You can write about your past self, the immediate self as well as the future self that is always on the way somewhere. You can project yourself into any time. You can play 'what if'. You can perform your thoughts and feelings on any subject; high school, college, previous marriages, jobs,... you can face down bullies, authority figures and always come out the victor.
It is an awesome art to be a comedian/comedy writer.
