I don't think necessity is the mother of invention invention, in my opinion, arises directly from idleness, possibly also from laziness. To save oneself trouble.
Dame Agatha Mary Clarissa Christie
Idleness is only fatal to the mediocre.
Albert Camus
Diligence is the mother of good fortune, and idleness its opposite never brought a man to the goal of any of his best wishes.
Miguel de Cervantes Saavedra
To have time was at once the most magnificent and the most dangerous of experiments. Idleness is fatal only to the mediocre.
Albert Camus
When they are not at war they do a little hunting, but spend most of their time in idleness, sleeping and eating. The strongest and most warlike do nothing. They vegetate, while the care of hearth and home and fields is left to the women, the old and the weak. Strange inconsistency of temperament, which makes the same men lovers of sloth and haters of tranquility.
Tacitus
There is a care for trifles which proceeds from love of conscience, and is most holy; and a care for trifles which comes of idleness and frivolity, and is most base.
John Ruskin
Smokers, male and female, inject and excuse idleness in their lives every time they light a cigarette.
Sidonie Gabrielle Colette
Idleness and lack of occupation tend -- nay are dragged -- towards evil
Hippocrates
Idleness, women, disorder, a foolish partiality for one's own native place, discontent and timidity are six obstructions to greatness.
Hitopadesa Hitopadesa
It seems to me that all of the evil in life comes from idleness, boredom, and psychic emptiness, but all of that is inevitable when you become accustomed to living at others expense.
Anton Pavlovich Chekhov
Life is best enjoyed when time periods are evenly divided between labor, sleep, and recreation...all people should spend one-third of their time in recreation which is rebuilding, voluntary activity, never idleness.
Brigham Young
Idleness is the great corrupter of youth, and the bane and dishonor of middle age. He who, in the prime of life, finds time to hang heavy on his hands, may with much reason suspect that he has not consulted the duties which the consideration of his age imposed upon him; assuredly he has not consulted his happiness.
Hugh Blair
Ye who, borne about in chariots and sedans know no fatigue but that of idleness.
William Cowper
Trouble springs from idleness.
Benjamin Franklin
It is idleness that creates impossibilities; and where people don't care to do anything, they shelter themselves under a permission that it cannot be done.
Bishop Robert South
