im in high school, i go to the gym a lot and workout hard. But im extremely lazy when it comes to schoolwork and anything other than the gym. Ive never studied for a test in my life, i never do homework at home, i have saturday detentions every week where i have to be there from 8-12 and i still dont do homework. Its like id rather stare at the wall instead of doing it.

I still maintain a decent gpa despite all of this. So thats not the problem but the problem is that i feel like all this laziness has made me feel stupider. Another thing i should add is that i absolutely dont care about anything, if i get a 60 on a test i wouldnt care, i dont care about detentions, i just dont care about anything and its getting on my nerves. im tired of not giving a fuck and being lazy.

Im doing aerospace engineering in college next year and ive heard its one of the hardest majors and requires a lot of studying. Im scared that ill continue being like i am in college and not do shit and drop out. How can i improve myself and start giving a fuck and stop being lazy?
