The manly part is to do with might and main what you can do

Our chief want in life is somebody who shall make us do what we can.

Nature arms each man with some faculty which enables him to do easily some feat impossible to any other

He who has acquired the ability, may wait securely the occasion of making it felt and appreciated, and know that it will not loiter

If I know your sect, I anticipate your argument

What we seek we shall find; what we flee from flees from us.
