Thomas Carlyle (17951881)
The most unhappy of all men is the man who cannot tell what he is going to do, who has got no work cut-out for him in the world, and does not go into it. For work is the grand cure of all the maladies and miseries that ever beset mankind,honest work, which you intend getting done.
