Probably harsher than should of been, but I see it this way.
0 – 24 - you wasted a lot of time
24 – 26 time to make up for it
Before I'm nice have to address this:
No one gives a shit about volunteer work, as someone else said. If you were 16, looking for your first job, this would be relevant. Also, a full course load? work 15 hours? Jesus man, do you know how many people work full time, have families and take a full load, all while paying for their home/kids?
Financially, it makes sense to stay at home; if you do, be a man about it. I'm a complete anomaly as far as how I did things and the order. Whereas, my brother, on the other hand, just got his license at 21, moved out of state for school, and is having a very difficult time managing his life. Our parents paid for everything of his, cell phone, food, going out to eat, gas (when he got his license), his clothes, EVERYTHING. If you are going to live at home, take responsibility for your bills, clean up after yourself, etc.
