You certainly are motivated and have a great head on your shoulders. I spent 6.25 years in the Army Security Agency in the 70s with 5 years in Asia and took ZERO civilian courses. My nephew, much smarter and motivated than I, joined the Navy and served six years enlisted as an Electronics Tech. The Navy sent him to nursing school and at 19 years time in service, he wanted to go to nurse anesthetist school (masters program) but the Navy didn't have an opening. He had met an Army Col that took an interest in him and promised, "If you jump ship to the Army, I will get you into our program." He did so, finished top of his class, served 2 years in the field, and returned for his PhD in neuroscience. He has 32 years of service now and serving as a LTC in charge of all nurse anesthetists at Walter Reed Hospital. He may have a shot at full bird Col but he is for sure set for a great career after retirement and is, like you, debt free on his education. Congratulations to you and best of luck in the future.
