Don't be so hard on yourself about not improving the world. I'm sure that you've positively affected someone. Even if it is a side-effect of your personal success, that allows you, for example, to leave a decent tip at a bar or restaurant. That decent sized tip helped the waitress make rent that month, and not get kicked out to the curb. Which kept her kids in a decent school district, where they learned a lot and will someday cure cancer. (Just an example).
