Having a daily routine keeps you in check with what is next to come. Here are a few points on the importance of daily routine in student life.
Attending lectures in school or college, then getting back home, finishing off homework, working on assignments, extracurricular activities, etc can all be very exhausting.
When a specific goal is set in front of you, it is natural that you follow through with that better than when you do not have anything to achieve.
If someone has their entire day plan, knows how to go about it, and is comfortable in their schedule, there are very skim chances of that person ever being worried or stressed about it.
When you are following a schedule, you are working on your studies and other academic things right from the beginning of the year.
When someone is working through a routine, they know what they have planned for the day. it encourages them to follow through with the time of the day and work around it.
While doing the same thing over and over again, every single day, you get a sense of understanding of whether the thing you are doing is good for you or not.
As mentioned previously, once you understand your mental and physical boundaries, you can set up your schedule around them.
