Mr. Herzog wrote a list of 24 pieces of advice. They are pretty fantastic, and some made me chuckle - see #2.
1. Always take the initiative.
2. There is nothing wrong with spending a night in jail if it means getting the shot you need.
3. Send out all your dogs and one might return with prey.
4. Never wallow in your troubles; despair must be kept private and brief.
5. Learn to live with your mistakes.
