Sorry, but I cannot take your philanthropy on climate change seriously when you have a massive short position against Tesla, the company doing the most to solve climate change.

Being a good corporate citizen is really important. We operate in a lot of different countries all around the world. We need to help build those communities from being good individuals and that is what I am trying to do in my personal philanthropy - is setting an example hopefully for other entrepreneurs who will build things in the future for how you should give back to the community and to the world.

In any business, the time to engage in philanthropy is when you are at your best.

Effective philanthropy requires a lot of time and creativity - the same kind of focus and skills that building a business requires.

Philanthropy should be voluntary.

The average Negro is born into want and deprivation. His struggle to escape his circumstances is hindered by color discrimination. He is deprived of normal education and normal social and economic opportunities.
