This is something that I never did as a student, but subsequently through years of employment have worked out that if I did it, I would have got so much more done and not sweated deadlines nearly half as much.
And that is treat it like a job, even a part time one. Just doing 4 hours a day at a regular time will get you so much done. It’s not un-creative to be structured. Sometimes (make that all the time) you have to just grind it out.
