Build habits that support you, and challenge the ones that do not.
We are all creatures of habit, so it is important to maintain routines that help you, but also to explore new ways of studying that could benefit you even more. You know your own life best, so use your experience to identify what already works, and have the courage to try new things, such as studying at home versus in the library or a study hall.
Finding the planning method that suits you takes time.
It may take some experimenting to discover what works best, but once you do, the effort will be worth it. There is no single way to plan your time, so stay curious and ask your peers how they do it.
We all continue to develop our study habits throughout our education, so nothing is set in stone. Once you find a method that works for you, the time you invested will truly be time well spent.
