Really interesting interview with David Karp about how he works.

Jason Fried writes about how to get really good at making money.

"No means you have to make tough choices that aren't always obvious at the time. No can be hard, even painful; it can lead to imagining what could have been. But when you make software, it's almost always a good idea to say no more than you say yes. Over time, you'll regret saying yes more than saying no. No?"
