I am not currently a student! However, time management is definitely something that I have struggled with in the past and am always learning how to do better.

What I've found to work for me (whether balancing school/a job vs. writing) is to block of dedicated time for whatever I think is important (for example, writing). I find that if you don't explicitly dedicate/block off time, it can be difficult to get to whatever you want to do. Also, I've found the technique of "time blocking" to be really helpful. Basically, you divide your day into blocks and assign specific categories of tasks to each block. I've found this method to work better for me than very granular planning or totally unstructured time.

Hahaha that was probably a more detailed answer than you were expecting, but I hope that helps! <3
