Something that I have found useful for managing my time in a busy schedule is to create an Excel sheet to break down my week and day to day activities. You can set your time increments to any amount of time you wish to break the day down by (15min, 30min, or 1 hr). After you have laid out each day and your activities such as work, meals, exercise, classes etc. it is helpful to color coordinate each item. Once you complete this you will find it easier to see what your days and weeks will look like. This is especially helpful for college students to organize time for classes, work, homework and extracirriculars.
