Richard Branson

"True success should be measured by how happy you are."

"Every success story is a tale of constant adaption, revision and change."

"When we talk about a 'successful' person,'some people think we're typically talking about someone who's got billions in their bank account, success is about happiness not wealth."

"My mother always taught me never to look back in regret but to move on to the next thing. The amount of time people waste dwelling on failures rather than putting that energy into another project, always amazes me. I have fun running all the Virgin businesses-so a setback is never a bad experience, just a learning curve."
