I doubt that simply donating money to charity is an efficient way to make the world a better place. There are studies that question, for instance, how much good all the money has done that we've given to developing nations.

It's definitely possible, I think, that creating a great video game might bring more happiness to the world than simply writing a check for a charity.

I am not saying, by the way, that being charitable is a bad idea. However, I do think you need to be strategic for it to be effective. For instance, it might be better to help a struggling neighbor or cousin by getting actively involved in their problems and helping them in a more involved manner. Or, if you have specific skill that can be helpful for a charity organization, that may be a better investment than just giving them money.

My point is, there is no simple, clear path to making the world a better place. We all have to actively think about how to make it happen. And it may happen in unexpected ways.
