“A young man should serve his parents at home and be respectful to elders outside his home. He should be earnest and truthful, loving all, but become intimate with humaneness. After doing this, if he has energy to spare, he can study literature and the arts.”

As quoted in Walt Disney, Magician of the Movies (1966) by Bob Thomas p. 116
Context: A person should set his goals as early as he can and devote all his energy and talent to getting there. With enough effort, he may achieve it. Or he may find something that is even more rewarding. But in the end, no matter what the outcome, he will know he has been alive.

Angry Young Man.

Variant translations:
Above all, do not lie to yourself. A man who lies to himself and listens to his own lie comes to a point where he does not discern any truth either in himself or anywhere around him, and thus falls into disrespect towards himself and others. Not respecting anyone, he ceases to love, and having no love, he gives himself up to passions and coarse pleasures, in order to occupy and amuse himself, and in his vices reaches complete bestiality, and it all comes from lying continually to others and to himself. A man who lies to himself is often the first to take offense. It sometimes feels very good to take offense, doesn't it? And surely he knows that no one has offended him, and that he himself has invented the offense and told lies just for the beauty of it, that he has exaggerated for the sake of effect, that he has picked on a word and made a mountain out of a pea — he knows all of that, and still he is the first to take offense, he likes feeling offended, it gives him great pleasure, and thus he reaches the point of real hostility… Do get up from your knees and sit down, I beg you, these posturings are false, too.
