A tram cannot discover every road! To discover every road, one must leave the predetermined roads!

To think the welfare and the goodness of the next generations is indeed a good ethics, but there is much greater ethics than this: To think the welfare and the goodness of the current generations, the very people of now! The reason is simple: Future may not exist, it is only a possibility, but the people of now are not possibility, they are here!

When everything is going greatly, you can never see the real faces of the people! Wait for the hard times to see the true face!

Man is full of energy; it is up to him how to use it! You can use your energy to do harm to people or to produce art and science; or you can use it for chattering or for deceiving people! By looking at the human history, we can easily say that man is guilty of wasting his energy mostly for stupid things!

Acquaintances are always abundant; friends are always scarce!

Visit the graveyards sometimes and read the headstone epitaphs! There is much to learn from the dark face of the life!

Between the truth and the faith, we must always choose the first one.
