Nie zawsze mów, co wiesz, ale zawsze wiedz, co mówisz.

[Klaudiusz]

We learn from experience that men never learn anything from experience.

[George Bernard Shaw]

God, grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference.

[Karl Paul Reinhold Niebuhr]
