at 26 was spent 50% of my time on a boat looking for oil around Europe and Africa, and the other 50% skiing, travelling, and generally having a tremendous amount of fun!
To be fair I was on quite a good salary for a 26 year old with no responsibilities/morgage/etc – so that helped – oh and the 6 months of the year I did work were pretty enjoyable too.
When I was 30 I quit and went skiing full time for a few winters. Now 41 and been back to a more "conventional" lifestyle with family, house, cats, mtb, etc for a few years – and to be honest that's pretty good fun too!
All that travelling stuff IS character building, it's not just a cliche – you learn lots about yourself and other people (especially how to deal/communicate with them)which is the kind of stuff that makes a difference when you embark on your next career challenge……plus I think in most cases it makes you appreciate your "lot" a bit more after seeing some of the more sh1tty parts of the world.
