If you're going to do it, do it while your young. I did a lot of traveling (IT related) in my early to mid 20s. I'm much older now and still do a fair amount of traveling, but its not nearly as fun when you have a family and other commitments. Being gone for weeks on end when you are young, never seemed to phase me; now I find travel to be necessary, and not nearly as exciting.

I spent ~40+ weeks on the road and moved all my stuff into my parents/storage and lived for a couple of years with little to no expenses. It gave me the opportunity for a bunch of new experiences and save a up a bunch of cash.

As for being on the road all the time; I loved it for the first two years, after that it did start to get old and you get burned out. There is definately a lot that can be learned (hard and soft skills) for being in the field and under fire most of the time. I think working as a consulting gives you the opportunity to get a lot of experience in a lot of different areas and environments. It also gives you the opportunity to build contacts and relationships all over the country and the world. You can always move to a desk job later on ;-).

Everybody needs to make their own decisions, but a couple years as a road warrior when you are young is the probably best (and easiest) time to do it.
