Things do not happen. Things are made to happen.
Be thine own palace, or the world's thy jail.
Know or listen to those who know.
Leap, and the net will appear.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
You never know what motivates you.
Quality is not an act, it is a habit.
The dog that trots about finds a bone.
Always desire to learn something useful.
One friend in a lifetime is much two are many three are hardly possible. Friendship needs a certain parallelism of life, a community of thought, a rivalry of aim.
