You've got to be brave and you've got to be bold. Brave enough to take your chance on your own discrimination, what's right and what's wrong, what's good and what's bad.
Great suffering brings with it the power of great endurance. When sorrow is deepest all the forces of patience and courage are banded together to do their duty. So while we are cowards before petty troubles, great sorrows make us brave by rousing our truer manhood.
The person who is right is the person who is the strongest, in this case, paradoxically, it's the cowards who are the brave ones, and they manage to impose their ideas on everyone else.
