SpinnerofDetroit. I'm currently sitting at work (i work in a call centre) and i work full time. on top of that i live at home so my expenses are almost zero. I also have started busking in the city. Am trying to develop and manufacture my own clothing to sell as well as my own line of toys and build my poi website and promote myself as a professional fire twirler to try and gete actually gigs and run paid workshops and, and , and ... collapse!
To be perfectly honest it's exhausting but brilliant at the same time. I don't get much sleep, about 4-6hrs a night. but i have serious plans to be able to travel perpetually and work or at least busk doing my arts while i travel to supporrt myself.
there are tons of ways to be able to travel the world for a pittance. My mate just got back form 8 months in europe and africa, he spent a total of $13,000 including everything. now he hitchicked, camped and couchsurfed basically everywhere in Europe which saves you a ton. I'm hoping to have over $20,000 saved before i leave in august including having paid for tickets and insurance. It's going to be very, very tough. i need to save another $10,000 - $12,000 in the next 3 months... which is why i'm working my ass off and doing all sorts of other stuff.
My advice for cheap long term travel is:
couchsurf,
hitchhike (if you're comfortable doing it)
eat cheaply (vego food is nutritious and cheap everywhere)
volunteer (e.g. Woofing)
get temp jobs (e.g. ESL teacher) - I'm currently waiting on a reply on a job as an ESL teacher in Spain for the 2010/11 school year.
