You have to be burning with "an idea, or a problem, or a wrong that you want to right." If you're not passionate enough from the start, you'll never stick it out.

Overnight success stories take a long time.

Do your best at every job. Don't sleep! Success generates more success so be hungry for it. Hire good people with a passion for excellence.

Customers don't measure you on how hard you tried, they measure you on what you deliver.
