The way to have a company that executes well is you have to execute well yourself.

We hear again and again from founders, that they wish they had waited to start a startup until they came up with an idea they really loved.

One of the keys to focus, and why I said cofounders that aren't friends really struggle, is that you can't be focused without good communication.

If someone is choosing between joining McKinsey or your startup it's very unlikely they're going to work out at the startup.

You can create value with breakthrough innovation, incremental refinement, or complex coordination. Great companies often do two of these. The very best companies do all three.

Someday, you need to build a business that's difficult to replicate. This is an important part of a good idea.

Most of the best hires that I've made in my entire life have never done that thing before.
