I am a rising college junior with major in the mathematics and an aspiring mathematician in the theoretical computer science and analysis. I wrote this post because I have been suffering from a problem regarding to my time management and planning skills. I have been using the planner and calendar apps in my iPad to schedule a planned course of events for each day; before I go to bed, I constructed the a fairly detailed daily-planning on my planner app, which also incorporates the calendar dates (marking important events like a dinner appointment with my professors, interview, exam dates, etc.). I listed a sample of my daily planning, which is from this Monday. 07:00 AM - 08:00 AM: Breakfast + Shower + reading a novel 08:00 AM - 10:00 AM: Study the introductory analysis (Chapter 2: Topology) 10:15 AM - 12:00 PM: Work on my undergraduate research (computational complexity theory) 12:15 AM - 01:15 PM: Play drums, eat lunch 01:30 PM - 03:00 PM: History class (Lecture) 03:05 PM - 04:00 PM: Review history lecture notes 04:15 PM - 05:15 PM: Weeekly meeting with my research adviser 05:30 PM - 06:30 PM: Work on my undergraduate research 06:30 PM - 07:10 PM: Dinner 07:15 PM - 09:00 PM: Study the introductory analysis (Chp. 2) 09:15 PM - 10:30 PM: Study the computation theory 10:40 PM - 12:00 AM: Improve my C++ programming skill 12:10 AM - 02:00 AM: Study the abstract linear algebra The problem with my daily planning schedule is not on the procrastination or tiredness: I absolutely despised the procrastination, and I also do not generally feel sleepy (and I do not like the sleeping). The problem is that allocated time periods for each event do not really meet up with the reality. For example, I could not even finish doing all problem sets on the sections of Chapter 2 for that Tuesday, studying the analysis. In the end, I realized that the allocated time amounts are almost always deviate from the reality. Furthermore, there sometimes are unexpected turn of events, such as sudden appointment with my friends to eat lunch together. For example, I suddenly got an idea, one that can be used to tackle one of the problems relating to my undergraduate research, during studying the linear algebra, which led me to stop studying the linear algebra and get back to my undergraduate research to see if that idea can be utilized. In the end, I could not study the linear algebra as I originally planned to do so Could you help me out by sharing your ideas and advice on my schedule, and sharing your methods of time management and scheduling for a day? How can a set up a daily planner that incoporates the classes, undergraduate research, self-studying, and meetings? Thank you very much for your time, and I look forward to hear back from you!
