Who waiteth for dead man's shoes will go long barefoot.
If you will call your troubles experiences, and remember that every experience develops some latent force within you, you will grow vigorous and happy, however adverse your circumstances may seem to be.
When the devil drives, needs must.
Half a loaf is better than none.
Be the day never so long, Evermore at last they ring to evensong.
Better to be happy than wise.
