Evaluating Use of Time

The first couple of weeks at college have been a time of great adjustment for me. I have begun to adjust to living by myself, the workload, and the immense amount of reading that is required, but I have yet to find the perfect balance of studying and activities. I have found it difficult to decide whether to go out with friends or study when presented with a spur the moment opportunity to go out. I don't want my grades to suffer because of decisions that must be made as frequently as this. Therefore, I realize that I must be able to better evaluate the situation and be able to easily deny an invitation if I need to be studying.
Aside from this difficulty I seem to be having, I feel that I have managed my time properly so far. It is definitely important to study and do homework every day, even if I only review notes or read a few chapters in my textbook. This is a good technique because it prevents immense amounts of studying or homework building up into an unmanageable and overwhelming amount. If I work a little each day I don't feel overwhelmed. Each day, I set aside at least an hour to devote to reviewing each subject area and spend a little time going over my agenda. By doing this, I always know when assignments are due and can contemplate when the best time to complete them is. I think that if I stay on this track of organization and continue to manage my time well, I will eventually learn to manage school and friends equally as successfully.
