I used to take on trust a man's deeds after having listened to his words. Now having listened to a man's words I go on to observe his deeds.
Worry not that no one knows you; seek to be worth knowing.
Don't be concerned others not appreciating you. Be concerned about your not appreciating others.
To one who is not eager I do not reveal anything, nor do I explain anything to one who is not communicative. If I raise one corner for someone and he cannot come back with the other three, I do not go on.
A man should say, I am not concerned that I have no place, I am concerned how I may fit myself for one. I am not concerned that I am not known, I seek to be worthy to be known.
Choose a job you love, and you will never have to work a day in your life.
