It may be the cock that crows, but it is the hen that lays the eggs.
Not every hen lay eggs. Not every hen that lays eggs gets them hatched. Not everyone born with greatness becomes as such. Go, hatch your eggs.
Be bold and boast, just like the cock beside the hen.
An egg today is better than a hen to-morrow.
I go on working for the same reason that a hen goes on laying eggs.
A pen is to me as a beak is to a hen.
