Nothing stops the man who desires to achieve. Every obstacle is simply a course to develop his achievement muscle. It's a strengthening of his powers of accomplishment.

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.

What you see, but can't see over is as good as infinite.

Poverty, we may say, surrounds a man with ready-made barriers, which if they do mournfully gall and hamper, do at least prescribe for him, and force on him, a sort of course and goal; a safe and beaten, though a circuitous, course. A great part of his guidance is secure against fatal error, is withdrawn from his control. The rich, again, has his whole life to guide, without goal or barrier, save of his own choosing, and, tempted, is too likely to guide it ill.

Pin thy faith to no man's sleeve. Hast thou not two eyes of thy own?

Wealth of a man is the number of things which he loves and blesses which he is loved and blessed by.

Properly speaking, all true work is religion.
