What should I do??

I have 4 siblings none of them went to college

1 is a LPN, 1 is a truck driver, 1 was in the military and is now a construction worker, and the other 1 works in a warehouse. If you ask me they’re all doing pretty good even though they didn’t go to college. I just graduated and I’m stuck on whether I want to go to college and become a nurse or join the Air Force. I kinda want to go to college and I kinda don’t. My mom says I won’t make it in college and college isn’t for everyone but I’m a smart person and I know that I could make it. My mom wants to me to join the Air Force but I don’t want to join because it’ll have her thinking that I wasn’t able to handle college and she’ll feel like she was right or whatever. She’s not right because I am able to do both of them I can handle college or I could handle Air Force. I feel that she wants to me to do Air Force because none of my other siblings never went to college and they’re all well off. Idk what to do.😕
