> So you felt free, because you could not get money?
No, of course not. Don't be daft. At that moment I didn't feel free, I felt trapped. But I got through it, had the time of my life, and learned that I could get by on less money than I thought I needed. I don't think I would ever have learned that lesson if circumstances hadn't forced me to.
Some people think freedom is access to unlimited resources. It's not. Freedom is the ability to achieve your goals with the resources you have at your disposal, whatever they might be.
> there are still plenty of adventures waiting outside
Yes, that's true. But nowadays you have to seek them out much more actively then you used to. Simply being far from home is not enough any more.
It's kind of like free climbing versus climbing with a rope and harness. Knowing that you might actually die (or have to sleep on the street) focuses the mind in ways that simply being on a rock (or being far from home) does not. Nowadays you have to work a lot harder to shed the harness.
