How a poor guy to travel around the world?

I managed to travel when I was a teenager. First of all I saved up money I got from doing a paper round. Then I was able to travel on a trip to Greece at age 14. Then at age 16 I worked as a Saturday shop assistant. I saved up to do more traveling. I went to the Netherlands when I was 17 years old with a friend. I dreamed about traveling around Europe but I didn't have enough money. To be able to afford to do that I got a job as a children's nanny in Finland. The wages were high and after my placement I went off around Europe. I did a long trip from 2001 to 2002. I was still quite poor after that trip in 2003 but I needed to go off traveling. I booked a flight on a no frills airline at left at 06.00. I slept the night on the floor at the airport awaiting that flight. I flew off and got to Trieste. I caught a bus to Dubrovnik overnight and arrived the next morning. I camped in my tent. I managed to pop down to Montenegro and up to Slovenia. I suggest working overseas or saving up. Good luck.

Equip yourself with a skill which is required all over the world (teaching, etc.) and then apply to countries that interest you and then keep traveling from one place to another after you complete your contract with each place. Do not let your dream die. Just focus on how to get there and you will. All the very best!
