Underachiever.

I always wondered what it felt like to never actually get to where you always dreamed you'd be. You spent your childhood just imagining your life and how happy you'd be, and then 40 years later you're just some...guy.

Not necessarily a bum. You might have some success, but its not the success you wanted. Nothing you have is what you wanted. You had to settle. What is that like?

Is it a sinking feeling? Is it like a hole that will always be there, unwilling to be filled? Is it a nagging in the back of your head that will never cease.

Not being able to live out your dreams must really, really, suck.
