He says:

Unconsciously we are forming habits every moment of our lives.

Some are habits of a desirable nature; some are those of a most undesirable nature.

Some, though not so bad in themselves, are exceedingly bad in their cumulative effects, and cause us at times much loss, much pain and anguish, while their opposites would, on the contrary, bring as much peace and joy, as well as a continually increasing power.

One of the things I like about the old classics is the way that the authors could pack such profound truths into so few pages and in ways that almost anyone can understand them.
