And herein lies the answer for whether or not you should study before med school.
Does you life suck [no friends, no money to travel, don't drink, no gf] ---> then study, you have nothing better to do
Does your life not suck [friends, money, drink, gf] ---> then don't study, go enjoy your life
Personally, my life sucked before, during and likely it will continue to suck after medical school. So instead of sitting on my ass doing nothing, wallowing in my sorrow about no gf before medical school I should have grinded the **** out of bros (there was no zanki at that time) and taken step 1 after 1st year of medical school. But each his own, I've found studying a good way to pass the time, so to all premeds reading this; there was a lot of memeing about introspection when I was applying, not sure if there still is. But do some introspection and figure out whether or not you hate your life. I hated my life so much I would have preferred studying, and I continue to hate my life so much that I prefer studying to doing anything else.
All of you people with wonderful lives need to stop assuming everybody's life is as good as yours, my life sucks, and if your life sucks too I recommend you study. It's a good way to pass the time.
