See, It's not just about the travel (although that would be lovely I'll admit)
Being a creative chap, having that money would allow me to explore many different avenues that previously would have been closed off. I'd look into getting involved more in film/music/art. I'd invest in and actively work on creative projects that really inspire and motivate me.
Of course, I can do that now but only on a much more limited scope as I have a mortgage to pay and all the kerfuffle that comes with that.
Basically, the money would allow me to open up my world without the financial worry. I would **** love it!
