In one sentence, describe what the following article is about:

Make a column of times on the left side of the page and a row of days of the week at the top. Begin with those activities that need to be done at a certain time every day. Based on your assessment above, slot in tasks based on the time you think it makes the most sense to tackle them. Also be sure to give yourself a break or several throughout the day. Hourly time frames are generally large enough. However, it can take time to get into the flow state required by some tasks so you may need 90 minute or even two hour blocks. Don’t forget to schedule in 30 minute tasks as well. Be careful of the tendency to wedge yourself in too tight. To create bigger blocks of time, you can merge cells together. It's difficult to predict how long each activity will take. So make sure your schedule can bend easily in one direction or another when need be. You also want to factor in a small buffer of time for unexpected delays. Also, don't fall into the trap of using your relaxation time as a "buffer" zone. Relaxation time should not be seen as a luxury; it should be treated as important as any other activity. It is generally helpful to print multiple copies -- put one on your refrigerator, one in your bedroom and one in the bathroom. Underline or highlight important activities. Use a different color marker for the separate areas in your life. You could use yellow for work, red for exercise, blue for school and so on. This way you’ll get a good sense of how your day is planned just by glancing at it. If there’s a lot of blue, for instance, you’ll know that you’re overloaded with school right now.

Summary:
