If you could change one thing about yourself what would it be?

I would like to be more open, and to be able to explain myself better.
Since I'm a pretty closed off person, its very difficult for me to explain things about myself.
Its also very difficult for me to community in general.

This is also true when there is something that I don't agree with, a situation I think differently about, or something that I want to do that others may think weird or even stupid (sometimes, these are the best ideas though!).
Being closed off and not open makes me not speak my mind, it makes me not do the things I would prefer to do.
So that's something that i would like to change about myself.
