Among mortals second thoughts are wisest.

I have lived in this world just long enough to look carefully the second time into things that I am the most concerned of the first time.

It is a good thing to learn caution from the misfortunes of others.

The bird alighteth not on the spread net when it beholds another bird in the snare. Take warning by the misfortunes of others, that others may not take example from you.

The chief danger in life is that you may take too many precautions.
