One thing to add: most charities in the inital stages are exactly like startups in the initial stages. They are great ideas but only that: ideas. Without dedicated people to run them and create things for them they will fall flat. Asking other people to believe in a non-existing charity is how those other people fail. You cannot give away all your business.

I remember a conversation I had many years ago with my father. He was wondering why I was interested in a particular endeavor in the military. He wanted to know why I did not pursue a job in business where I could make a lot more money.

My reasoning was this:

If you spend 40 to 50 hours per week of your waking period doing your job, is that not the most time you spend doing anything? It is more than you eat, more than you spend time with friend, and more than you even spend time with your spouse. Is it not the point of life to find something you love to do so much that to do it is the reward itself? If you cannot do something you really enjoy, really have passion about, then is that not a waste of your time? By doing something you really love it outweighs the benefit of doing something you really hate just so you can make more money for the small amount of time you have left in the week.
I was talking about passion. He got it and agreed with my decision. I still believe that today, and Ed writes about it here. Pursue your passion.
