Another option for the OP: go to school and get your undergrad in engineering. Get a PPL along the way. If you end up liking both engineering and flying, consider pursuing a job as a test pilot.
While there are a lot of people that go from the military into the test pilot career field, it's not the only way. My boss went the civilian route to become a test pilot; it's a great job, generally pays well, and is both fun and mentally engaging.
