How do I become a good programmer while working through college?

If I live on campus as a CS student and work at part-time a fast-food restaurant right across from the campus, how do I find the time to practice my craft every day in an efficient manner? Right now, I have nothing to my name but an incomplete amateur OO Python rpg. I didn’t start coding until my first semester. How do I decide what “X” to do every day so that I can do it and improve?
