Get yourself a job and you can go holidaying around the world on. Considering most countries are still stuck in an economy recession now is the best time to travel around the world. Most of the airlines have $6000 world tours which is bloody cheap...We have Bali holidays selling for AUS$340 return, absolutely a bargain, not exactly a 'round the world tour' but for long weekends, it is a great place to enjoy a few days being pampered.
Going on world tour is really very difficult as the financial things will top the list for sure. I was amused on meeting some poor travelers making it to the world tour ! how they manage money? will teer be any trust sponsoring them?
Some people use Air Mile points that they've saved up for a long time. Some people combine their money. Some people just planned it out a few years ago and they saved up all the way to achieve what they wanted.
There are ways that people make quick money. You can even travel to one area and make money there easily... Not alot of places have the same minimum pay wages.
