Exercise, work on a cruise ship for a year. Then you will appreciate your opportunities. And don’t major in what you don’t like. I changed my major 5 times in college because I hated STEM fields and got a degree in English Lit. It’s ok to be not motivated by academic setting. That does not mean you will not be motivated outside academic settings. I was very unmotivated at school, but super motivated in setting up and making my biz a success. I actually find it weird some kids like to study because for me I need to see practical need and opportunity first before I start to get motivated to try to find solutions.
