My number one rule in business, and in life, is to enjoy what you do. Running a business involves long hours and hard decisions; if you don't have the passion to keep you going, your business will more than likely fail. If you don't enjoy what you are doing, then you shouldn't be doing it.

The amount of time people waste dwelling on failures rather than putting that energy into another project, always amazes me

Having no regrets makes way for the best piece of advice I can give - don't be afraid of failure.

If we can just get young people to do the same as their fathers did, that is, wear condoms

We have a business that some people feel pollutes, and I happen to agree with them. ... And so on the basis of trying to do good and, you know, hopefully turn a profit, what we did was we pledged that we'd put all the profits from our airline business into trying to develop clean fuels.

I am always working on the go.

Whatever business you are in, every company can shoot for the start in their own way.
