Any country is hard to govern, even a very small country. It's not a question of whether the country is large or small. It's a question of how you relate to the work, to what extent you feel responsible for it. Russia is also hard to govern.

Russia, actually, is not just a large country, it's a great country. I mean its traditions, and its cultural particularities.
One of the characteristics of successful scientists is having courage. Once you get your courage up and believe that you can do important problems, then you can. If you think you can't, almost surely you are not going to.
