This is some advice from that great section hiker, Henry ‘Bilko’ Thoreau.
Lead a life of simplicity and independence apart from social organization and material civilization. That will save you a ton of dough.
Front only the essential facts of life, and see if you can not learn what it has to teach and not, when you come to die, discover that you had not lived. You are already on the right track for this. It will not make you alot of money but it will make you a rich man.
Simplify, Simplify. It’s not so much how much income you have, it’s more about what you are spending your money on. As Garlic, Feral, Leanin’ and tom indicated spend less save more.
My final advice; get a job any job that pays well, work like a dog and save as much as you can. You can stay motivated long enough to fund your trip. And you will be a better man my friend. Good Hiking, HBT:boy
