I agree with h311m4n.  If you have no debt or other obligations, do it.  Just make sure you have a good plan in place.

I'm fairly new to mining, however, I'm an experienced travel hacker.  There are tons of websites and pvt forums dedicated to the topic.  I've traveled the world (in 1st class) and stayed at some of the nicest resorts and hotels for free for years now.  If you could combine the two "hobbies", I think you'd do quite well.  Google Flyertalk and the blog frequent miler for a good place to start with all of that.  Beware, Flyertalk is huge and confusing to noobs! lol
