Advice to a Beginning Graduate Student
I once asked UMESH VAZIRANI how he was able,
as an undergraduate at MIT,
to take 6 courses each and every semester.
He said that he knew he didn't have the time to work out his answers the hard way.
He had to find a shortcut.
You see, Umesh understood that problems often have short clever solutions.
There's a wonderful quote from ANATOLE FRANCE:
"A University Student"
-- and this is especially true for a PhD Student --
"should know something about everything
and everything about something."
