What tribes are, is a very simple concept that goes back 50 million years. It's about leading and connecting people and ideas. And it's something that people have wanted forever.

Sign your work...If you're not proud of it, don't ship it. If you are, sign your work and own the results. We'll know who to thank. If you work for a place where work goes unsigned (internally, in particular) it's worth asking why.

You have to find a group that really desperately cares about what it is you have to say. Talk to them. They have something I call otaku. It's a great Japanese word. It describes the desire of someone who's obsessed to, say, drive across Tokyo to try a new Ramen noodle place 'cause that's what they do, they get obsessed with it.

Great boss is challenging people in the right way. Leading, not managing. Supporting them by giving them both a platform they can count on and expectations they can stretch for.

And in a world where we have too many choices and too little time, the obvious thing to do is just ignore stuff.

Who's going to stop and pull over and say, oh, look, a cow? Nobody.
