Pick a really small subset of the problem and focus on that.

It may seem boring at first, but let the chase of winning excite you, along with the money. Odds are you get bored because you're not interacting with customers and/or making money from it. I've fallen into this trap before. Seeing money come into your bank account or have customers contact you will get you insanely pumped. It's not about the money in a greed sense, but in the "i've done something people find valuable sense".
