I did a long post some time ago about time management. It boils down to this: there are plenty of hours in a week to socialize and enjoy recreation if you have a weekly/monthly planner or calendar and you use it always. This can be electronic or on paper.
At the beginning of the semester, when course syllabi are handed out, mark the dates and times of every exam, every paper due date, every class meeting (lectures, labs, and discussion sections). You can’t just work day to day or week to week, because you’ll never prepare adequately for exams or papers or research projects.
Check the plan every day, morning and evening. Amend it, update it with new information. Check off assignments you have completed, classes attended.
Start with the basic fact that there are 168 hours in a week (24x7). Then consider that you’re likely to be in class – including lectures, labs, discussion sections, etc. – about 15-20 hours. This leaves you with 148-152 hours that are initially UNSCHEDULED. So what to do? Fill the remaining calendar with needed preparation for class (reading, problem sets, language labs, etc.). List the specific classes/subjects you are devoting each hour to. And use your daytime hours between classes to fill up what is essentially a 40-hour work week Monday through Friday. Then add hours to evenings as needed when projects are due or the reading is particularly heavy. And the add hours for clubs, recreation, films, etc., on top of your coursework.
Suppose you have some weeks when your classes and preparation, reading, etc., add up to (egads!!) 60 hours??! That leaves you with a mere 108 additional uncommitted hours!!! PLENTY of time for recreation, sleep, eating, hanging out, etc. And you will be able to do that without feeling guilty about it if you’ve used your core waking hours productively. This doesn’t mean there won’t be times when different assignment due dates will crush you. You might even have to put in a few long days, and even “overnighters” to meet deadlines. So what? Believe me, you won’t be alone! But there will be plenty of time for everything else if you’ve spent your daytime hours productively.
I am by nature NOT a planner. But I realized when I was about to enter college that the rule of thumb was that I would have to spend 2 to 3 hours out of class on my schoolwork for every hour in class. I attended a college that is notorious for the work load – not the number of class hours but the amount of reading and studying required. Even so, with about 15 hours in class, I could manage the work if I put in 30-40 hours outside of class. If I used the space between classes during the day – in the library or my dorm room or some other study place – I managed the heavy load.
But I also had fun because even in the weeks that were most demanding of my time, there was time for other things if I had a working plan.
