23M, i need an advice on how to succeed in what i’m occupied with, despite lack of time

I’m 23M. I’m currently working full time, so i can be financially independent and also help my parents. But at the same time, i study engineering and it just gets tough for me because it feels i dont have enough time for it. I also go to gym at least 4 times a week. I live alone and take care for everything in my house, to add that up. Although the quality of my life has been improved since i’m more occupied (in comparison when i used to depressed and did nothing for myself), i feel i’m not able to catch up with everything in life properly due to lack of time and conditions.

What can yall suggest me, so i can be able to succeed in everything i’m working with right now?
