Try making a schedule for yourself... one that is possible and good for you. (one that includes work, school, homework time, free time, work out time?, etc) Depending on if your work schedule is consistant or different shifts all the time, it may be easy or hard. This could stand as a good foundation for your start to having better time management skills.
Give yourself time for homework and free time (if possible). I used to be so inconsistant with time management until I gave myself a schedule and followed it. Since, I have less stress and worries on my shoulders, along with being more productive.
