Why couldn't it have been done 2 years ago, and why will 2 years in the future be too late?

Why now, why is this the perfect time for this particular idea, and to start this particular company?

I care much more about the growth rate of the market than it's current size and I also care if there's any reason it's going to top out.

One of the great and terrible things about starting a start up is that you get no credit for trying.

To get the very best people- they have a lot of great options, and so it can easily take a year to recruit someone.

Remember that you are more likely to die because you execute badly than get crushed by a competitor.

You need unstoppable people. You want people that are just going to get it done.
