"Well, I am going to do this thing that makes money and then when I am rich I will give back"
Is bullshit. You either give back or you don't. It's not a question of time and money.
I try and do as much local charity work as I can, I try to be present when listening to friends and family. I try and treat my wife and my family as the most important people in the world so that they can bring that love to other places, but I hear what you saying.
I want to be working on things that change the world. I think at some level, we all want to be.
Thank you for asking / sharing.
