I find it very difficult to think of mistakes; not that I don't make any but because I was brought up to look only at the good things in life ... As for what lost the most money, probably Virgin Cola. It is still No 1 in Bangladesh though.

My interest in life comes from setting myself huge, apparently unachievable challenges and trying to rise above them.

It's all about finding and hiring people smarter than you. Getting them to join your business. And giving them good work. Then getting out of their way. And trusting them. You have to get out of the way so YOU can focus on the bigger vision. That's important. And here's the main thing....you must make them see their work as a MISSION.

Complexity is your enemy. Any fool can make something complicated. It is hard to keep things simple.

You must have the courage to trust your instincts and be ready to question what other people don't. If you do that, you can seize opportunities that others would miss. Believe in yourself, and use everything you can - including the obstacles - to propel you along the road to success. Who knows what you might achieve?

Learn to raise capital by any means necessary. That's your primary job as an entrepreneur. You must continually raise capital from family and friends, banks, suppliers, customers and investors.

I doubt that I would have been successful in my career and happy in my personal life if I hadn't prioritized health and fitness. Staying active ensures mental preparedness and the courage to try new things. It helped me to stay focused on work but also to have fun and try new approaches and explore new places. That's the spirit behind Virgin Sport - we wanted to introduce fitness activities that are enjoyable, accessible and part of your overall lifestyle.
