Apart from values and ethics which I have tried to live by, the legacy I would like to leave behind is a very simple one - that I have always stood up for what I consider to be the right thing, and I have tried to be as fair and equitable as I could be.

Some foreign investors accuse us of being unfair to shareholders by using our resources for community development.

No matter what your mission is, have some notion in your head. Forget the model, whether it's government or nonprofit or profit. Ask yourself the more important question: Is my mission improving the world? Are you sure about it? Seek to disconfirm that all the time. And if you can, change your mission.
