All confidence which is not absolute and entire, is dangerous. There are few occasions but where a man ought either to say all, or conceal all; for, how little so ever you have revealed of your secret to a friend, you have already said too much if you think it not safe to make him privy to all particulars.
Nothing can add more power to your life than concentrating all your energies on a limited set of targets.
Your mind, which is yourself, can be likened to a house. The first necessary move then, is to rid that house of all but furnishings essential to success.
You can do only one thing at a time. I simply tackle one problem and concentrate all efforts on what I am doing at the moment.
Gather in your resources, rally all your faculties, marshal all your energies, focus all your capacities upon mastery of at least one field of endeavor.
Concentration is my motto - first honesty, then industry, then concentration.
Never believe anything until it has been officially denied.
There is not a flower or bird in sight, only a small screen on which lines are moving, while the child sits almost motionless, pushing at the keyboard with one finger. As a learning environment, it may be mentally rich, but it is perceptually extremely impoverished. No smells or tastes, no wind or bird song (unless the computer is programmed to produce electronic tweets), no connection with soil, water, sunlight, warmth, the actual learning environment is almost autistic in quality, impoverished sensually, emotionally, and socially.
When an individual fear or apathy passes by the unfortunate, life is of no account.
He who feels no compassion will become insane.
