I saw a very interesting video on what leads to success. Richard St. John spent 7 years and 500 interviews to determine these are the secrets:

Passion -Be driven by your passion

Work - It's all hard work

Good - find one thing and get good at it

Focus - focus on just one thing

Push -yourself physically, mentally

Serve - serve others something of value

Idea - find a good one

Persist - The number one reason for success
