Telling family I’m joining the army

I decided to join the army. I am thrilled and so ready for this challenge. I am in college right now but not enjoying it. Life is too short to do something you don’t love. So I plan on doing active duty and do college courses to get a degree. My family (especially my mother) would not approve of this choice. She wouldn’t think I could make it. She is a firm believer in college for me. I am married and my husband is in the military as well so I’m not sure why she doesn’t like this choice to me. Anyway, I am concerned about telling her. I’m thinking about giving my family an army ornament or mug to break the news to them. Any ideas?
