Big companies have trouble with innovation. Innovation is about bad ideas, or ideas that look like bad ideas. That's the fundamental thing.

As a company gets big, the information that informs decision-making gets massive. Depending upon the prism through which you view the business, your perspective will vary. If two people are in charge, this variance will cause conflict and delay.

You read these management books that say, 'These are the hard things about running a company.' But those aren't really the hard things. The hard things are when you have to layoff half your company, or you have to fire your best friend. Or you have to figure out a way not to go bankrupt.

Look - this is the terror of being a founder & CEO. It is all your fault. Every decision, every person you hire, every dumb thing you buy or do - ultimately, you're at the end.

Nobody knows how to be a CEO. It's something you have to learn. It's a very lonely job.

As long as people are clear on what they need to do and what's going on, you're very likely to succeed. When nobody is clear, then you're guaranteed to fail.
