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

Philanthropy should be voluntary.

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.

I have always looked at business as an opportunity to make a difference in people's lives.

Philanthropy is commendable, but it must not cause the philanthropist to overlook the circumstances of economic injustice which make philanthropy necessary.

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.
