The most important study tip is to set aside a certain time to study and stick to it.
By scheduling a 2 hour study window, when that time is up, you are free to walk away and get on with your family and job and other pieces of life that you put on hold.
Since you have a fixed amount of time instead of a random window (this afternoon I’ll work on my paper) you are more likely to get to work right away.
Hint: This tip works in all areas of your life. Give yourself a set amount of time and get your task done and move on.
