Donate back to the organizations and communities that have helped me. Hopefully, this is around 10% of my yearly salary once I start making money. Also, beyond quantitative means, I am currently trying to become a doctor so I can volunteer my time in places with limited medical resources. For example, I can volunteer through Doctors Without Borders. This would happen closer to the 20-year benchmark because I still have to go through undergrad, medical school, and residency before becoming an attending doctor.
