Great question. So while I am not in the medical field, I have to balance long hours with many other commitments and hobbies which is not easy to do, but is very much possible. As a consultant I am expected to work 50+ hours a week plus working from home sometimes if things get really serious. Because of my long hours and other work commitments I am definitely pressed for time which impacts my personal life for sure. I have had to become really disciplined with my time so that I am able to balance many different priorities. There are times where I am not able to see my friends on the weekends due to a work related activity or times during the week where I wish I could spend time running errands where I am not able to do because of a work commitment. There is a cost to everything and work can sometimes interfere with other aspects of my life, but it's not the end of the world. I usually am commitment-free on the weekends and can spend the time doing whatever I like to do. I always try to plan out my weekends and schedule time so that I am able to do the most amount of things and see the most amount of people.
It is important to stay organized and on top of things because you don't want to overcommit yourself to things by accident. If I am seeing a friend on Saturday, I will try and schedule Sunday for something else. It can be tempting to focus your time on one aspect of your life, but you are going to need to space out seeing one person/doing a certain. In order to remain involved in your hobbies and have friends you are going to have to divide up your time. It is never easy to say "no" to people but it is something that you are going to have to do.
Also, consider limiting the number of different things that you are involved in if possible. If you are able to limit the number of commitments you have, the more time you will have to spend time doing the remainder of the things you'd like to do. This is by no means easy or fun, but sometimes it is required in order to give yourself time to do things that are the most important to you. If you are truly committed to one hobby or time commitment, eliminating aspects of your hobbies/extracurriculars will grant you more time to focus on a singular thing.
I hope this helps and I wish you the best of luck!!
