Never confuse motion with action. 

<>- Ernest Hemingway

The greatest loss of time is delay and expectation, which depend upon the future. We let go the present, which we have in our power, and look forward to that which depends upon chance, and so relinquish a certainty for an uncertainty.

<>Lucius Annaeus Seneca 5BC-65AD, Roman tragedian, philosopher, and counsellor to Nero  

It is not because it is so difficult that we do not try something, it is because we do not try that makes something so difficult.

<>Seneca 4BC-65AC, Roman writer and moralist  

Whatever you do, or dream you can do, begin it. Boldness has genius, power and magic in it.

<>Johann Wolfgang von Goethe 1749-1832, German poet, novelist and dramatist  

It is impossible for a man to learn what he thinks he already knows.

<>Epictetus c. 60-120, Roman philosopher  

 

We are what we repeatedly do. Excellence then, is not an act, but a habit. 

<> Aristotle
