Trouble brings experience, and experience brings wisdom

It is strange how often a heart must be broken before the years can make it wise

A wise man makes his own decisions, an ignorant man follows public opinion

Before God we are equally wise and equally foolish

If a wise man behaves prudently, how can he be overcome by his enemies? Even a single man, by right action, can overcome a host of foes

Good people are good because they've come to wisdom through failure. We get very little wisdom from success, you know.

We seem to gain wisdom more readily through our failures than through our successes. We always think of failure as the antithesis of success, but it isn't. Success often lies just the other side of failure.

The wisdom of the wise and the experience of the ages, may be preserved through quotations

Learning acquired in youth arrests the evil of old age; and if you understand that old age has wisdom for its food, you will so conduct yourself in youth that your old age will not lack for nourishment

The oldest trees often bear the sweetest fruit
