Is the secret to not overthinking social interactions (and thus reducing social anxiety in some people) just being less bored???

I feel so lazy and unproductive that it is depressing me. I find it so hard to go to sleep at decent hours and wake up early, i just want to stay home and play games and do nothing but at the same time, i feel like i need to socialise and go out and see more things.. I also feel like im wasting my knowledge like im in a good course, im learning medicine and im not even putting it to good use! My brain deserves a not so lazy body.. Im not being fair with my brain and I apologise. I am too lazy to use my intelligence and I know im wasting potential and i could be an excellent doctor but im pretty sure i wont be more than average
