There is definitely time for extracurriculars in medical school and its all about being able to manage your time well so that you can enjoy other things. I answered another question about whether you do have free time in Medicine to engage in other activities, you can read my full answer here.
The way I balance my time is by creating myself different priorities, medical school is obviously a top priority. So, every week I’ll give myself a list of study related goals and I’ll spread them across each day of the week. Once I’ve worked through them, then I’ll allow myself to focus on some extracurriculars. Setting myself goals based on what I want to complete on a daily basis is what helps me balance my time, enabling me to engage in extracurriculars.
I think it’s all about finding a routine that works for you. In my first two years, there was a period of time in which I found it helpful to consistently wake up at 5 am every morning and start working through my goals for the day at that early hour. My day (in terms of sessions) often started at midday so following this routine meant I had often finished all my targets before beginning my day. That worked amazingly for me, because after my sessions I could completely relax and do other extracurricular activities.
