1) beating everyone else at their own game. i am hyper competitive
2) money. i'll be retiring (in 14 - 20 months - after working for what will be a total of roughly 7 years in this industry), and will never have to work again. ever. that's an extremely powerful motivation for me. now that it's so close, it keeps me going harder then ever.
3) to be honest, i simply love the internet. i know i'll always be involved with it, but likely not in a bottom-line-business sort of way, once this current phase of my life is over.
