Time for Ancient Greece to speak! :
Sophocles
"If you are out of trouble, watch for danger."
"There is no success without hardship."
Socrates
"The nearest way to glory is to strive to be what you wish to be thought to be."
''Look death in the face with joyful hope, and consider this a lasting truth: the righteous man has nothing to fear, neither in life, nor in death, and the gods will not forsake him.''
''The unexamined life is not worth living.''
Epictetus
"Practice yourself, for heaven's sake, in little things; and thence proceed to greater."
Aristotle
"It concerns us to know the purpose we seek in life, for then, like archers aiming at a definitive mark, we shall be more likely to attain what we want."
"To perceive is to suffer."
''Young men err in everything by excess and vehemence, contrary to the precept of Chilon; they do all things too much, since they love and hate too much, and likewise in everything else. They fancy and insist that they know all things, and this is why they overdo everything.''
Pindar
"Success for the striver washes away the effort of striving."
