Anthony Trollope
Never think that you're not good enough yourself. A man should never think that. People will take you very much at your own reckoning.
Nothing surely is as potent as a law that may not be disobeyed. It has the force of the water drop that hollows the stone. A small dainty task, if it be really daily, will beat the labours of a spasmodic Hercules.
Success is the necessary misfortune of life, but it is only to the very unfortunate that it comes early.
