To take no account of oneself, but always to think well and highly of others is the highest wisdom and perfection.
By two wings a man is lifted up from things earthly: by simplicity and purity.
In the morning fix thy good purpose; and at night examine thyself what thou hast done, how thou hast behaved thyself in word, deed, and thought.
Pass no rash condemnation on other peoples words or actions.
If you want to learn something that will really help you, learn to see yourself as God sees you and not as you see yourself in the distorted mirror of your own self-importance.
