yes it does.

do phd because you like learning new things. dont do it because you think it will get you more money or better future.

phd must be able to learn for the sake of learning.

do also get some experience outside of academia. dont confine yourself in the university. sometimes the way people think inside research labs does not match with rest of the industry.

and yes, this belong more in education essential. and this subforum should be renamed to something else. i'm pretty sure most of us dont have phd despite acting in general like smart asses
