Getting involved in some sort of club is a great way to refocus your energy and avoid getting burned out on studying. With a higher course load it's difficult to get involved with extracurricular activities. However, these activities may help to add structure to your daily routine that school alone may not be able to provide. Often times we will procrastinate more when we have a lot of time on our hands. Whether you function more or less efficiently when pressed for time, there are time management techniques which can help.
Balance is the key word with regard to time management.
It is important to find a balance between what has to be done for school or work and what needs to be done for your personal health and wellness. There are time management techniques to help you balance academic responsibilities and social activities. These techniques also create the structure needed to be more productive. Getting organized is the first step. Making lists can be really helpful to make sure that you can get everything done and squeeze in all of those other things that you want to do.
