Great companies are built on great products.

In almost any industry, if you're passionate about doing a great job and making people that buy your product or service as happy as possible, it's really fulfilling.

You have to be pretty driven to make it happen. Otherwise, you will just make yourself miserable.

Boeing just took $20 billion and 10 years to improve the efficiency of their planes by 10 percent. That's pretty lame. I have a design in mind for a vertical liftoff supersonic jet that would be a really big improvement.

Brand is just a perception, and perception will match reality over time. Sometimes it will be ahead, other times it will be behind. But brand is simply a collective impression some have about a product.

If humanity doesn't land on Mars in my lifetime, I would be very disappointed.

I've actually not read any books on time management.
