I am an MS student and I also have a part time job. I am facing the same producticity problem that has bothered me during my Bsc.

As to organization, I have a calendar on my desktop showing important events like exam\homework and the rest of the studies related tasks I keep in my head because there are not too many of them (although they are very time consuming e.g. reading chapters XYZ from book W)

Getting a degree in general is quite a burden and demands mastering complex concepts daily. This may be enhancing my productivity problem. What happens can be descriped in the following steps:

1. I have a set of tasks to complete with various deadlines (homework, study material etc.).
2. Before time pressures me I tend to lose focus. Then I end up doing something more attractive like watch a movie\series.
3. Once I've had one "portion" of fun (say an episode of some series), I can't force myself to make the shift towards studying. The task at hand seems so complex or even scary, especially compared to the immediate satisfaction received by watching the episode.
4. I end up having more portions of fun with little or no studying at all.
5. Time begins to pressure as I've wasted days that were initially planned for task completion.
6. Deadlines get very close. I am then forced to engage the tasks.
7. I work under a lot of pressure, with little sleep and the outcome is not as good as I would've liked in the best case. (low exam score, pulled an all-nighter to manage the h.w. deadline etc.)

This has happend to me over and over again for as long as I remember myself. Even when the outcome is destructive(and it often is) it does not prevent the situation from happening the next time. Juggling studies with a job makes deadlines much shorter so I feel pressured much sooner but the whole process still happens.

I would love some advice.
