I have a friend, a mentor of sorts, introduced to me by another mentor of sorts (who, come to think of it...was introduced to me by another mentor of sorts....but I digress...), who articulated the point that business and personal interactions aren't necessarily neatly separated, and that's a good thing.
I completely agree with this. Now that I've been at this work-for-myself thing for 6 months (yee-ha, btw), I have the ability to work on what I want to work on. With who I want to work with, more importantly.
And you know what...I only reach out to the people I really enjoyed working with. Sure, I'm networking my head off, but I have the luxury of pursuing engagement with folks I liked before, and that I know I'll enjoy working with again. I've got that handful of folks in my past that I could reach out to...big positions at big places...movers and shakers, if you will...but if I didn't like working with them then, why would I now?
I can't detach people from business. People DO business. I like people. Most, anyway.
