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

No matter what you choose, build stuff and be around smart people.

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.

Founders are usually very stingy with equity to employees and very generous with equity to investors. I think this is totally backwards.

Obsess about the quality of the product.

In general don't start a startup you're not willing to work on for ten years.

Everyone starting a startup for the first time is scared, and everyone feels like a bit of an imposter.

No growth hack, brilliant marketing idea, or sales team can save you long term if you don't have a sufficiently good product.

You have to be decisive. Indecisiveness is a startup killer.

Execution gets divided into two key questions: 1) can you figure out what to do and 2) can you get it done.

If you don't need it yourself, and you're building something that someone else needs, realize you're at a big disadvantage.

We should not give up and we should not allow the problem to defeat us.

I'm not running to manage the decline of this great country. I'm running to make real changes in D.C.

We've been speaking English as a second language so long that we've forgotten it as our first.

You know you're putting a good thing out into the universe when you put on glitter.

When our vices desert us, we flatter ourselves that we are deserting our vices.

Prisons are needed only to provide the illusion that courts and police are effective. They're a kind of job insurance.

Fiction is experimentation; when it ceases to be that, it ceases to be fiction.

God was feeling sardonic the day He created the Universe. So it's rather up to at least one man every few centuries to pop up and come just as close to making him swallow his laughter as possible.

We forget to remain focused on the things that really matter.

Only failure makes us experts.
