Happiness is a roadside ...

Happiness is a roadside flower growing on the highways of usefulness; plucked, it shall wither in thy hand; passed by, it is fragrance to thy spirit. Trample the thyme beneath thy feet; be useful, be happy.
 Martin Farquhar Tupper

Quotes from the same author

To be accurate, write; to remember, write; to know thine own mind, write. And a written prayer is a prayer of faith, special, sure, and to be answered.
 Martin Farquhar Tupper
None is poor but the mean in mind, the timorous, the weak, and unbelieving; none is wealthy but the affluent in soul, who is satisfied and floweth over.
 Martin Farquhar Tupper
Man liveth from hour to hour, and knoweth not what may happen; Influences circle him on all sides, and yet must he answer for his actions: For the being that is master of himself, bendeth events to his will, But a slave to selfish passions is the wavering creature of circumstance.
 Martin Farquhar Tupper
To-morrow is that lamp upon the marsh, which a traveller never reacheth; To-morrow, the rainbow's cup, coveted prize of ignorance; To-morrow, the shifting anchorage, dangerous trust of manners; To-morrow, the wrecker's beacon, wily snare of the destroyer. Reconcile conviction with delay, and To-morrow is a fatal lie; Frighten resolutions into action, To-morrow is a wholesome truth.
 Martin Farquhar Tupper
A good book is the best of friends, the same today and forever.
