I learned a lot of similar lessons. I like his point about how they're too busy because investing isn't their primary focus. I actually found this infuriating at first because they promised to be really helpful, but because they were so hard to reach they actually became really expensive.<p>He's dead on about the momentum. I had 4 angels lingering around, and it wasn't until I was like "ok, everyone else is investing, act now or you'll miss your chance" that I got 2 of them to close.<p>And for seeing measurable goals... they don't care at all about business metrics, they see your progress as being measured by bright and shiny objects. Just crank out code and get users, don't dither on marketing plans or building competencies because that's not something they see as valuable, nor as progress.<p>Hope that my testimonial adds something to the reading experience of the article. :-)
