Depend upon it, Sir, when a man knows he is to be hanged in a fortnight, it concentrates his mind wonderfully.
(Samuel Johnson : Boswell's Life of Johnson)
The one serviceable, safe, certain, remunerative, attainable quality in every study and pursuit is that of attention. My own imagination would never have served me as it did but for the habit of humble, daily, toiling attention.
(Charles Dickens : 1812-1870)
The weakest creature, by concentrating his powers on a single subject, can accomplish something. Whereas the strongest, by dispersing his over many, may fail to accomplish anything.
(Thomas Carlyle : 1795-1881)
I think concentration as a kind of stamina or mental tenacity, the result of a consistent purpose. It is the art of making our minds behave. It requires choice : fixing our mind and energies on one thing to the exclusion of others. The men who achieve important positions in life depend less upon their natural aptitudes than on this acquired ability to fix the attention on any specific problem and to hold the mind to that problem until they have seen it through.
(Frederick B. Robinson : Former President of the College of the City of New York)
Success is attained through an integrated mind which has no otherness. Whatever be our goal, the mind must be integrated. It must keep that one goal in view and eliminate all other thoughts that deviate from the main purpose. Otherwise we will not be successful in any field. The full force of the mind should be with us for success to come.
Frog's optical field of vision is like a black board wiped clean. The only images it receives are objects that directly concern it : its natural enemies and the food it needs. The frog is never distracted by unimportant things. It is aware of essentials only - for survival and safety.
