When your young and starting in the working world and have the education, work ethic and oppertunity why wouldnt you? With proper planning you could set yourself up for life. One young man that we know took this oppertunity is well into a six figure salary, investing, owns his own home and no longer doing "boonie" work at 29 yoa. Has he had to make some tough choices, yep. But, haven't everyone in their chosen career fields?
Speaking of the war zone/Halliburton crowd, I've known many that have left good paying careers with solid benefits to make big $ money in the short term. The ones with focus and a plan retired early. The ones that just wanted a new car, new wife, new farkles are still working.
