if you had to choose ship building or auto mechanic or realestate which would you choose? or airplane mech?

i was an electronic / jet engine / fuel systems tech for 5 yrs in navy. i worked on cars and houses all my life. now i have to go to college with my gi bill. im tired of doing a lot of work and making nothing. i am a great cook and was thinking chef or nurse or car mech or airplanr mech or realestate agent / builder combo. i have expierance in all these fields. i just dont know what to do. i dont like coming home dirty and greeting family messy. im scared to go to college as im a slow learner and taught myself the asvab and my ged. but i did get a 62 on my asvab. coming from someone who dropped out after 8th grade thats not too bad. i love cars and work great with them but also like to work at my own pace. dont really want to be stuck in a hot kitchen all day. i have built home and hotels and showed properties before and fixed them up. i dont know what to go to school for. im thinking buisness for at least 2 years. am highly motaviated indivuidal and a leader. when not in lead igetlost

Realestate, You will make more money and do less work.
