I understand that he needs to know that not all people are fair, not all are sincere. But teach him that if there is a scoundrel, there is also a hero, if there is a selfish politician, there is also a devoted leader. Teach him that if there is an enemy, there will also be a friend.
Teach him that a dollar earned is more valuable than five dollars found.
Teach him to play, as well as to enjoy victories. If you can, keep him away from envy, teach him the secret of a gentle laugh. Let him understand early that pleasing the bullies is the easiest thing to do.
If you can, teach him to be interested in books... And give him also free time so that he can ponder the eternal secrets: the birds soaring in the sky, the bees appearing in the rays of the sun, and the flowers at the green foot of the hill.
When he is in school, teach him also that it is much more honorable to endure failure patiently than to cheat. Teach him to trust his own ideas, even if those around him say that he is wrong.
Teach him to be gentle with gentle people and cruel with cruel people. Try to give my son strength so that he does not give in and does not follow the crowd that has crossed over to the winner...
Teach him to listen to all people, but also teach him to consider what he hears from the perspective of truth and to take only the good.
If you can, teach him to smile in moments of sadness. Teach him that it is not shameful to cry. Teach him to mock cynics, and to avoid flattery.
Teach him to sell his brain and muscle power for the highest price, but never to sell his heart or soul.
Teach him not to listen to the howling crowd, but also to stand up and fight if he thinks he is right.
Be gentle with him, but without excessive tenderness, because only after the test of fire are the best qualities of steel revealed.
Let him be brave, so that he becomes intolerant of bad things. Let him be patient, so that he becomes brave.
Teach him to always believe in himself, because then he will always have faith in humanity.
