For me also, I just flat out don't have time to always be dressed to impress etc. With the exception of this year (and it's not really a exception because of interviews), I have usually been on the grind. I don't have time to be playing games like phoenix mentioned when I am trying to balance grades, MCAT, school functions, volunteering, while also maintaining some semblance of a normal life (as normal as a premed's life gets).
I am all about getting to know someone by first being their friend and seeing where the relationship goes from there. Unfortunately, that's initially not enough for most people, and at this point in my life, I can't invest a significant amount of resources in only trying to obtain a good catch. Don't get me wrong though, I will do whatever it takes to keep her though, I just need to be met halfway
