I have this hanging in my cubicle at work. It started out as a joke directed more towards my coworkers than myself, but recently it seems to apply to me more and more:
Sometimes I just sit and stare at it when I'm tired of staring at my computer screen, and I think, "You're right. Nobody is paying me to believe in my dreams, but they should be."
So it when it comes down to it my inspiration is reverse engineered from a snarky Demotivational Poster.
