I graduated as a kid with 2 retirees in my psych classes who told me getting their degree was one of the most important, rewarding things they had ever done.
Also,, nowadays you can travel abroad in dozens of countries, take English-language courses and get accredited degrees in every field for very affordable tuition fees, as in 90% cheaper than the US.
While you're attending those schools, your cost of living will be dramatically lowered as well.
If anyone wants details, talk to me here or in Travel.
I still travel because learning about the world is fun(and cheap) and every time I'm in a new country it's no small measure of reassurance that most people are kind.
