I love this thread! I am feeling the exact same. I worked a boring office job for a year and a half, saved up and moved to Aus for a year. It was the best year of my life!
Now I'm back working at a different boring office job and all I can do all day is sit and think about travelling again.
I'm finding it hard to save money this time, but I'm hoping to travel Europe in spring 2012...if I can wait that long.
I have to plans to do the same thing after that and come back to work a job I hate.
It makes me feel a whole lot better knowing there are people out there like me
