Someone at work once accused me of "always trying to be the most interesting person in the room" because I was doing fun stuff with my weekends (at least fun to me). I know he was trying to put me down in some way, but all I could think was "yeah, kind of, you ppl are all super boring."
In a 1L event years ago, someone asked “what sort of hobbies could I pursue in my 1L summer that would look good on resumes?” I can’t remember how long after that I left the room, but not soon enough.
If your non-metrics selling point is something spectacular, you’ll know it. Otherwise, try to be the kind of person who is more interesting than someone who picks their hobby to advance a resume. Live a life. You’ll have plenty of time to not live a life once you’re practicing.
