Nice find and great vid! All that videography would have been a distraction to me but appreciate that he had it to share
Did something similar on smaller scale when I was younger than him, but also did army, undergraduate and post-graduate and subsequently spent a lifetime traveling and and/or living 'abroad' in my line of work including some very 3rd world experiences. Agree as some have pointed out that you definitely take a hit financially - compound interest can kick your butt, but with the right will there is always a way and whilst I know I could probably be a lot wealthier now if I had taken an alternate path, I would not give up a single moment and really have no regrets (that and saving like a mad person has put me in a decent place!
) = live for now and repeat!
