Welcome! You must know there are plenty of nuclear subs in the Navy so that could be a great career. If you do join the military, they also have MWR programs (morale, welfare and recreation) that basically allow you to rent sailboats all over the US; the world, too, I imagine. As to sailing now, keep on searching but don't jump on the first junk you see. You'll find the right boat to learn on. Look at lots of them and try not to bite off more than you can handle. A smaller boat = (likely) fewer problems, which will also cost less to maintain in the long run. We've gotten Cal 20s here on the West Coast for free, which are really great first-timer boats that have been sailed to Hawaii and other places and back. So, find something that is (truly) sound and then put the money into rigging and sails, which will cost you $$, but it can be done reasonably. Make sure you know what to do to stay safe when all else is breaking loose around you. Never be shy about asking lots of questions. The people here are great. But do filter and do your due diligence on the answers. Ignore the ornery ones
And....always....always....never stop learning.
