My students often tell me that they don't have "enough time" to do all their schoolwork.

My reply is often a brief "You have as much time as the president." I usually carry on a bit about there being twenty-four hours in the day for everyone, and suggest that "not enough time" is not an acceptable explanation of not getting something done.

Once in graduate school, I tried to prove to one of my professors by saying that I was working hard. His answer to me was, "That's irrelevant (无关的). What's important is the quality of your work." Since then I have had time to think carefully about the "hard worker" dodge (诀窍), and I have come to some conclusions- all relevant to the problem of how much time we have.

If you analyze the matter, you can identify two parts of the problem: There is, of course, the matter of "time", which we can think of as fixed. Then there is the problem of "work" during that time. But, as my professor suggested, it's not how hard one works but the quality of the product that's important.

That led me to a new idea: the quality of the work. That concept is perhaps best explained by a sign I once saw on the wall in someone's office: "Don't work harder. Work smarter." There is a lot of sense in that idea.

If you can't get more time, and few of us can, the only solution is to improve the quality of the work. That means thinking of ways to get more out of the same time than we might otherwise get. That should lead us to an analysis of our work habits. Since "work" for students usually means "homework", the expression "work habits" should be read as "study habits".

Then, as a smart student, you will seek to improve those skills that you use in study, chiefly reading and writing. If you learn to read better and write better, there are big benefits that pay off in all your studies.
