With a little practice, clunky awkward phrases become flowing bits of information.

“All that a man achieves and all that he fails to achieve is the direct result of his own thoughts. 

In a justly ordered universe, where loss of equipoise would mean total destruction, individual responsibility must be absolute. A man’s weakness and strength, purity and impurity, are his own and not another man’s. They are brought about by himself and not by another; and they can only be altered by himself, never by another. His condition is also his own, and not another man’s. His sufferings and his happiness are evolved from within. As he thinks, so is he; as he continues to think, so he remains … 

And you, too, will realize the vision (not just the idle wish) of your heart, be it base or beautiful, or a mixture of both; for you will always gravitate toward that which you secretly love most.”

- JAMES ALLEN
