A lot of people want to make a difference in the world. But I can tell you from personal experience that the best you can do is to try and make a difference in a single life. Find someone who desperately needs something you have: Street smarts, intelligence, business wisdom, a shoulder to cry on, etc. Give THAT to a single person and you will make a world of difference to them. Don't try to change the world. Make life better for a single person at a time. Your ripple will make the world better in ways you'll never fully be able to realize.
