A habit of making a backup copy for important files. I always record my classes so that I have something to rely on whenever I have to refresh a topic. It helps a lot especially during finals because I have to study from the very beginning for our departmental subjects. With that, I always make sure to create a backup copy on my hard drive because I once had an incident where my computer got corrupted and I lost all of my files (a heartbreaking moment for me). It is also convenient for me to store it on my hard drive since our internet connection is not that reliable so uploading and accessing it online will only make it difficult for me. #RandomThoughts
