Let us define “free time (0)” to mean something like “time where a person has no particular appointments or where she has no duties that need to fulfilled within that time.” So, for example, an hour break between classes would be an example of free time (0).
There is another sense of free time that is not captured by free time (0). Let us define “free time (1)” to mean something like “time where a person doesn’t have anything that she even could be doing during that time.” For a person with free time (1), that person would be able to say, “I don’t have any assignments hanging over my head right now.” Of course, for such a concept to be useful, it may be necessary to specify a domain over which it applies—so one might meaningfully say, “I have free time (1) with respect to my job, but not with respect to my chores at home.” It would be rare indeed to have free time (1) without qualification.
So for example, a student between semesters, or at the beginning of the summer break has free time (1) as far as school is concerned. And if we consider the previous example, it’s easy to see how a person might have free time (0) in an hour break between classes, but how that person will not truly have free time (1) until after she writes her final exam and hands in all her assignments, because until then, there is always more preparation and work that she could do.
When I worked at my 9-5 job this summer, I was lucky because I had a lot of free time (1) with respect to my job, even though I didn’t really have as much free time (0) as I had when I was in school. That is to say, I didn’t have much free time (0) because my job dictated that I spend the hours between 9h in the morning to 17h in the afternoon at my desk, doing particular things. I had little free time (0) in that sense. Contrarily, I had plenty of free time (1), compared to being at school. At school, really, the only time you get free time (1) is when you are between semesters (and sometimes not even then). At work, I had free time (1) from my job every night. When I left my work, the responsibilities of the office stayed at the office. I never had homework. I never had exams. There was a clear line separating my work-life from the rest of my life. In fact, as far as work was concerned, the set of hours that made up my free time (0) was exactly co-extensive with the set of hours that made up my free time (1).
Now that I’m working on my thesis full-time, I have more free time (0) than I have ever had in my life, especially now that my office hours and conferences are over for the semester. The trade-off is that I don’t ever have any free time (1). There is always something else I could be reading, or something I should be writing or a revision to my thesis that I should be working on. There is no time that I couldn’t point to on my day-timer of which I couldn’t say, “maybe I should use this time for my thesis.”
Here’s where it gets interesting: I believe both that I’ve never truly had any free time (1) while in school, and that somehow this experience of writing my thesis means that I have even less free time (1) than I had before. This is obviously a contradiction (to think that I never had something before and that now I somehow have less), so it means that my conception of free time (1) is too simple.
So let’s now re-define free time (x) as being time with no particular appointments or tasks to do, when there is up to (1-x) times a full workload’s responsibility “hanging over your head.” And x can be any real number between 0 and 1, inclusive.
Awesome. The previous definitions still hold, pretty much, and it gives us the language for describing the difference between my experience in undergrad and my experience with my thesis.
My experience in undergrad was that while I never actually did experience free time (1), I often experienced free time (1/2) or free time (3/4). I would come to a point where I only had a very few things that I could reasonably do (after all, there’s a finite number of review questions for your chemistry test) and so I wouldn’t feel the weight of the full workload’s responsibility. At the beginning of each semester in my undergrad, I would have free time (x) with a higher value for x than at the end of the semester.
With my thesis, on the other hand, even though the whole thing is divided into chapters, it’s more like one long paper than a series of short and connected ones. For example, I have to make sure that any changes I make to one chapter will agree with the other chapters. My supervisor uses the analogy of building a railroad. I have to make sure that the tracks at one end (chapter one) line up with the tracks at the other end (the last chapter). My thesis is a whole, in some ways, and so I think that’s why my experience with regard to free time is different than it was during my undergrad. I sometimes do experience a little bit of free time (1/4), though, but that’s after I submit a draft of a chapter or something.
In conclusion, right now I have lots of free time (0), no free time (1), and only little bits of free time (1/4), every once in a while.
And for the record, I did write this while procrastinating on writing my thesis.
