I am big fan of David Allen's Getting things Done approach. I am just going to leave a quote of his here:

"Frankly, I don't like people in terms of productivity.
They're a pain in the butt.
For the most part, people get in your way in terms of getting things done.
Except for three things, as far as in my experience.
The three things I have to have people to do.

1. Number one, emergencies. And I try to minimize those, but there are times
   where you just gotta engage with people to handle that.


2. Number two, warm human contact. I found people a fairly critical element to that experience. (audience laughing)


3. Number three, option development and brainstorming.

Those are the only three things I hang out with people for.
Now, by the way, that doesn't mean I don't like people. As a matter of fact, the way I'm wired, my idea of success in my life is a vast majority of my time is hanging out with way cool, incredible folks BSing about incredibly creative things."
