How to be happy at business, a Venn diagram by Bud Caddell. From his writeup:
We can’t determine how to make enough money from the things we want to do, and do really well. I’m constantly surprised at what can be monetized. And on the web, there’s a market for almost anything. But this problem requires you to rapidly iterate your positioning and the type of clients you serve. Often, we’ll get transfixed on a single direction early on (because we’re desperate to solidify our business) and we’ll miss our chance to radically experiment with the market.
A short and sweet synopsis of what we should all be striving for, not just if you have your own business.
