I mentioned earlier my idea for a personal finance site that — obviously — had already been done by mint.com. Now it looks like I’ve also missed the chance to at least cash in indirectly by buying Mint’s stock.

They were acquired for $170 million earlier this week by Intuit, maker of the Quicken software.

Seeing as they were noticed by NYT at least a year ago, I guess I should take consolation that I’m a few years too young to have started this company, and probably also to have cashed in on its stock.

Lesson learned: you have good ideas, if only because obvious ideas are good ideas. The hard part is getting off your lazy bum and implementing them. THAT’s what gets you rich.
