I was in the same spot you're in now. But I was in school at the time (so perfectly broke). The one good thing is that my school was one that has a good reputation for getting you a job. So I got one fairly well. Isn't the best pay for what I do, but it's alright. The first year I had some things to pay off, get together, etc. (long story). But then I could start saving full throttle. It's been nearly a year since then..in another 5 months (just under!) I'll have enough to go to Europe, SE Asia, and enough to go back to the UK and (hopefully) get a job there for a while. It took about two years...though it could've been done in one, I think..I'm 22 now. You can do as much as you want, as long as you have the will for it. Don't give up on it; start on saving up - you can go a long way in just two months. But in the meanwhile, I agree with the above - you can try teaching English abroad, they're always looking for teachers, and practically anyone can do it. There's also volunteer work for different organizations, but you would have to look them up and make sure they're not scams (some of them are). Most of all, don't lose hope on it. You'll get there sooner or later.
Lots of luck
