When I wrestled, I would set aside the time to wrestle, so that in my mind it didn't interfere with my study time. If I'd say, "I'm going to study this many hours, then I'm going to go work out and wrestle," then when that time comes, you don't feel like you should be doing something else. That helped me psychologically. But otherwise? When I'm wrestling, I'm not studying the universe. And when I'm studying the universe, I'm not wrestling.
