I have to admit that I am constantly trying to think of The Next Big Thing: the next web fad, the next big technology, etc. I'd love to come up with the next Facebook or Google. Software is my passion, and I'm always trying to thing of new ways to use software to help people and/or make money. Most of my ideas never pan out, but it doesn't stop me from thinking of new ones.
I'll admit that it is a little optimistic to think that I'll come up with the Facebook or Google, but it would be so cool if I did. All I need to think of/invent/find out/predict the next big thing on the web. I find that it is easy to come up with ideas, but most of them are slight twists on things that already exist. Trying to come up with something truely unique and something that people want is not so easy.
Of course, part of what drives me is the thought of a potential revenue stream, it would be great to come up with something that generates income. But that is not my only draw. I just enjoy writing software, and if I can make a little extra money doing it, then even better. The last aspect is nerd cred. How cool would it be to be the next Mark Zuckerberg or Larry Paige.
Hopefully I'll come up with The Next Big Thing soon, but it's taking a lot of work.
