-: I think one of the things I learned here
was to not be afraid of asking the hard questions
and working on challenging problems,
becoming very comfortable with complex systems.
I learned from my mentors that it's okay to work in a field,
in a discipline that everyone considers
too hard and too challenging.
It hasn't been done before.
It's okay.
You can be the first to do it.
That never deterred my mentors,
and I think I took some of that away with me.
Sometimes I worry that it's not a good thing
to always pick the hard problems.
I just want something easy
or something that's going to work out.
But I think that's not a good long-term strategy,
and so what I always try to do is not be afraid
of the unknown and the hard and difficult problems.
It's okay, yeah.
