Commitment is not letting people down. That's very important in life.

I drink about 30 cups of tea a day. I'm a complete tea addict.

For a successful entrepreneur it can mean extreme wealth. But with extreme wealth comes extreme responsibility. And the responsibility for me is to invest in creating new businesses, create jobs, employ people, and to put money aside to tackle issues where we can make a difference.

Breaking the rules and challenging convention is in the DNA of every successful entrepreneur. Doing things differently and solving problems with new, innovative and fresh approaches are the very reason many start-ups are able to compete and sometimes outpace the established market leaders.

All successful people - not just entrepreneurs - have got things wrong over and over again before finding the right solution.

Above all, you want to create something you're proud of.

Most "necessary evils" are far more evil than necessary.
