It's kind of a rule of thumb for me to self-doubt going into any kind of project. I always think that I shouldn't be doing it and I don't know how to do it and I'm going to fail and that I fooled them. I always try to find a way out.
I hate shaving. It's much easier to just do a little stubble, but my wife and daughter like it when I'm clean-shaven. If you see me with a clean face, then you know I'm in the kissing mode!
