There is nothing assured to mortals.

Nothing is secure but life, transition, the energizing spirit.

Security is the chief enemy of mortals.

Without a measureless and perpetual uncertainty, the drama of human life would be destroyed.

Many people think that by hoarding money they are gaining safety for themselves. if money is your ONLY hope for independence, you will never have it. The only real security that a person can have in this world is a reserve of knowledge, experience, and ability. Without these qualities, money is practically useless.

The desire for safety stands against every great and noble enterprise.

Security will produce danger.

It is better to have a permanent income than to be fascinating.

No one has a prosperity so high and firm that two or three words can't dishearten it.

Whatever has overstepped its due bounds is always in a state of instability.
