Important life decision...?

first a little backround info-- i am 17 and am graduating high school january 18. i have braces that are scheduled to be on for about another year. i am a level 2 krav maga practitioner (its an israeli martial art) and live with my mom who is a staff seargent in the marines. i am trying to decide between the military or being a krav maga instructor.

-military option--- i would join the marines with the intention of getting to MarSoc. i took the asvab and scored a 90 2 days ago. my plan would be to go in enlisted, and if i decide to stay in the marines for the full 20 years, i would use the officer commisioning program to become an officer.all in all, this would give me good benefits, good pay, a steady income, lots of training, and lots of influence.

Krav instructor--- my instructors have offered to send me to instructor school. the next one is january 19. if i pass, i will begin working for my instructors with a starting pay of 20/hour. depending on when i will be able to get to the next level of instructor, i could be a level 3 instructor by the end of june or july. at that point i would be getting paid 30/hour. i would also owe my instructors about 6000 for the school. (it costs my instructors 2000 each time they send me to instructor school). as a level 3 instructor, i would be able to work about 20, maybe as much as 30 hours per week. that means i should be done paying the instructors in 2.5 to 3 months. after that, i will be making somewhere around 600 a week. that only comes out to being a little more than 30k a year. it is more than i would make in the military, but the military also provides housing, food, medical insurance, etc. my mom would probably let me continue to live with her until i become a higher level instructor and get paid more.

i dont know which option to go with. i love krav maga, and i love helping people learn. on the other hand, ive wanted to be a marine all my life. technically, i could do both, but doing one would delay progress in the other. any advice?
