Please, do not start believing you will be making a difference through charity.

I observed rich people in the past that out of some half-conscious guilt started thinking they need to give back in some way. But they don't want to be inconvenienced by doing it personally or by evaluating which people deserve a donation or have an important material problem solved, by themselves. They prefer to unload their guilt -- or the need to feel good about themselves -- through a 3rd party. Basically, buying goodwill and good conscience with money.

That's not giving back.

I have known several rich people and they go through a very similar process. It's very saddening to observe.

If you want to make a difference with money -- go out there. Physically! Meet people with less. Talk to them. Ask them what is the hardest thing in their lives at the moment. Ask them what's a regular concern for them. Do that 100 times, or 500 times. Understand their struggle. Many would just squander the money in a week, even if you gave them a bag of it. Try and aim your efforts and money where it will truly count.

It's not an easy thing to do. But it's a worthy cause to pursue, much more worthy that a random charity.

Apologies for off-topic.
