No one really knows enough to be a pessimist.

Nothing is enough for the man to whom enough is too little.
You cannot teach a man anything; you can only help him find it within himself.
One is always a long way from solving a problem until one actually has the answer.
I cannot teach anybody anything, I can only make them think.
Unhappiness is the ultimate form of self-indulgence.

When you joyfully surrender to the wisdom of uncertainty nothing goes wrong.
If you're the smartest person on your street, maybe it's time to find a new street.
If you expect nothing from anybody, you're never disappointed.
To conquer fear is the beginning of wisdom.
