My penis, I hate it. It's just far, far, far, far, far too big.
(Rubbish) jokes aside - I'm too hard on myself. I'm doing well - I have a good job, amazing wife, beautiful children, am pretty much financially secure, and yet I constantly worry that I'm not doing enough, not good enough at my job etc. etc. I also agonise over every mistake and imperfection.
Meh, thankfully I have an enormous penis to make up for it.
