around the world

Blogger of nicolekiss decided to put down all the commitments and went off travelling around the world for 2 years. Her post did make some urge(a lil) of me for doing that too. Seeing all the sights while you are still young,to be frank I had never ever think of that. It never come across my mind of doing that. Am wondering how much does it actually cost for me to travel around the globe?? How much longer I need to work in order to gather the amount of that minimum expenses. Is it that easy to be done with those minimum cash? Maybe I had been worming too long in my comfort zone in order for me to take that big step. Okla...i do not have the courage and of course the $ :p
