I thought about this; but there really is no practical way is there?

I could save up money but for how long? by the time I got enough money to travel the world I’ll be old and dying.

I want to travel the world YOUNG and healthy with the power to tackle hiking expenditures like the Grand Canyon and Mount Everest.

Should I get a career that makes me capable of traveling or what? Or should I be a vagabond who sneaks onto sail boats and what not?

You just have to go about it the right way.
I had a plan similar to that.
After I finish this year of school I’m doing now, I’m going to get a job for a year…theeen use that money to travel, and then come back after a year of traveling and go to university.
Yes, traveling is expensive…BUuuuut if you do it right..then it’s not really. Like, I was thinking hitch hiking to some places…and also you can get train tickets that you just pay for once and they allow you to go ANYWHERE really for a certain period of time. It’s way cool.
If you don’t get like a ton of fancy expensive plane tickets then you should have enough money:D
