Where can I find a "nurturing" engineering graduate school?

“just as you had that “Aha!” moment, that there is so much more you don’t know beyond that…and that can be very frustrating at times.”

Makes sense.

“Finally, no professor is willingly going to let you hang around for 4 years getting a master’s degree.”

If that’s truly the case, then I guess I’m screwed for now, as far as going to grad school.

Regardless, thanks for your replies.
