Professionals. What does it take, and am I crazy?

Hey guys so a little bit of back story.

I'm 23, currently active duty in the Navy stationed out in Colorado. I've been doing photography for about 2 years now and I'm finally starting to become confident in my work. I have found that I tend to favor lifestyle/portraiture more so than any other type of photography so that has been my big focus lately.

However, I've got two years left of my enlistment and the passion I have for photography has fostered the idea of getting out of the Navy and pursuing photography as a career considering it's something I love and get excited about. Plus the micromanaging within the military gets old. Quick.

I'm not looking for a magical recipe for success or anything, but what I am hoping for is insight from professionals, on what characteristics or traits can help a photographer make a decent living if not thrive in the industry.

I'd also like some input on what degree or field of study would be most beneficial in the realm of photography. My gut says marketing but I could be wrong.

My service to this country has given me access to benefits I'm truly grateful for because I don't have to worry about racking up debt to earn my degree. Which will allow me to focus on some intern/assistant jobs just to continue growing my abilities while I get the formal education piece.

I think all this sounds fairly realistic and possible but my family is petrified by the idea so I just wanted some second opinions from people actually doing it.

TLDR: Want to get out of the military and pursue a career in photography.

Thanks for taking the time to read my short essay lol
