Men, like nails, lose their usefulness when they lose direction and begin to bend
Walter Savage Landor
A public man must never forget that he loses his usefulness when he as an individual, rather than his policy, becomes the issue

Promptitude is not only a duty, but is also a part of good manners; it is favorable to fortune, reputation, influence, and usefulness; a little attention and energy will form the habit, so as to make it easy and delightful

Alex Campbell
There is no excellence without labor. One cannot dream oneself into either usefulness or happiness
Liberty Hyde Bailey
Two important characteristics of maps should be noticed. A map is not the territory it represents, but, if correct, it has a similar structure to the territory, which accounts for its usefulness
Alfred Korzybski
Nothing in this world is so good as usefulness. It binds your fellow-creatures to you, and you to them; it tends to the improvement of your own character; and it gives you a real importance in society, much beyond what any artificial station can bestow
Sir Benjamin Collins Brodie
