My wife and I are 25, and found ourselves in a similar position when we first graduated. When I graduated and moved to take my job, I was so poor I actually ran out of gas and didn't have any money to fill up because I was waiting on my first paycheck.
We started a scholarship at our university to give $1,000 annually to support college students who were student teaching and participating in internships. My wife and I both struggled financially through our experiences, but they provided us with the foundation to land our current jobs. We decided to give back to those who were going through similar times.
The real eye opening thing for me was getting a year-end bonus check larger than my total annual wage at the university. I had no excuse not to give back. Since that time, we have seen at least 5 other young couples from our school who followed our lead. That has been the most rewarding part.
We chose to support kids and college students. Many of them need the help.
