I wanted to be an inventor like Nicola Tesla and make enough money by selling shareware (like Notch did with Minecraft) that I could have a lab like Tony Stark and change the world.
Now I sit at home all day scouring stackoverflow.com hoping to get one hour of real work done per day on my contracting gigs to pay the mortgage. My to-do queue is so full that I can't see the day when I'll be able to work on my own projects. I'll be out of money in a few months and probably have to get a "real" office job again.
