do you think you're an expert on your field? or just about as competent as your advisor? like i just want to know how it feels, i spent lots of hours on this one computer game , i can sort of feel what's like to be very good at one thing. i wonder if that's how you feel after completing a phd? obviously the ceiling is much higher in academia. but, i'm asking because i'm about to leave school, i still hope to have a phd one day, the sad thing is that, i'm not very focused right now and need a break from school. i can handle the material for my master program, but i feel like i'm not learning much at all. i guess, my question is, how long does it take you to become one of the best?
