Any tips on how to change mindset and be productive is welcome

I will cut right to the chase. I took a resolution for this year to be more productive and get a better job than the shit one I am stuck with. Last year I tried to be productive by trying to achieve small goals but I failed and the only thing I actually did consistently was going to the gym, other than that I didnt learn any career uplifting skills or anything that would've made me a productive person. I watched tons of productivity videos, yapped to my friends, yapped to chatGPT, tried certain productivity apps but nothing helped and I also understood that I am my own enemy and I also struggle to come out of my comfort zone. So as the title suggests, Any tips is welcome. I just want to be relieved and I really regret wasting my college days instead of trying to learn something to shape my career.
