If you want good living conditions then don't join the Navy. The travel is good but living conditions are horrible. You will sleep in a huge room with about 100 people with no air conditioner. If you don't get along with the person next to you then your boss will say "If you don't get along then I will make you two share the same bunk". The room ventillation is so loud it sounds almost like a jet. They turn the ventilation off for drills and weapons movements and the temperatures soar to 130 or 140 degrees sometimes.
If you want more money become an Entrepreneur. A person I went to school with took home just under $2,000,000 last year after taxes from the fast food chain that he owns.
