A man of knowledge lives by acting, not by thinking about acting.

человек знания живет действием, а не мыслью о действии.

a man of knowledge has no honor, no dignity, no family, no name, no country, but only life to be lived, and under these circumstances his only tie to his fellow men is his controlled folly.

Think like a man of action, act like a man of thought

Think like a man of action, act like a man of thought. — Henri Bergson

человек знания живет действием, а не мыслью о действии. Он выбирает путь сердца и следует по этому пути. Когда он смотрит, он радуется и смеется; когда он видит, он знает. Он знает, что жизнь его закончится очень скоро; он знает, что он, как любой другой, не идет никуда; и он знает, что все равнозначно. У него нет ни чести, ни достоинства, ни семьи, ни имени, ни родины. Есть только жизнь, которую нужно прожить.

True knowledge lies in knowing how to live.

The learned man who does not act up to his knowledge is like a patient who describes the qualities of a medicine without using it or like a hungry man who describes the taste of a food without eating it.

— a knowledgeable man is a free man, or at least a man who longs for freedom.

A man lives by believing something; not by debating and arguing about many things.

How can a man know what is good or best for him, and yet chronically fail to act upon his knowledge?

He Who Knows And Knows That He Knows Is A Wise Man - Follow Him;
He Who Knows Not And Knows Not That He Knows Not Is A Fool - Shun Him

He who acquires knowledge and acts up to it and teaches it to the people is noble to the angels of heaven and earth. He is like the sun which illumines itself and gives light to other things. Such a man is like a pot of musk which is full of fragrance and gives fragrance to others. He who teaches knowledge to others but does not himself act up to it is like a notebook which does not benefit itself but benefits others or like an instrument which gives edge to iron but itself has got no edge, or like a needle which remains naked but sews clothing for others, or like a lamp which gives light to other things but itself burns.

None of our men are 'experts.' We have most unfortunately found it necessary to get rid of a man as soon as he thinks himself an expert because no one ever considers himself expert if he really knows his job. A man who knows a job sees so much more to be done than he has done, that he is always pressing forward and never gives up an instant of thought to how good and how efficient he is. Thinking always ahead, thinking always of trying to do more, brings a state of mind in which nothing is impossible. The moment one gets into the 'expert' state of mind a great number of things become impossible.
