As one grows older, one becomes wiser and more foolish.
Pain makes man think. Thought makes man wise. Wisdom makes life endurable.
To acquire knowledge, one must study; but to acquire wisdom, one must observe.
Inner wisdom is more important than wealth. The more you spend it, the more you gain.
Those who wish to appear wise among fools, among the wise seem foolish.
Like an ability or a muscle, hearing your inner wisdom is strengthened by doing it.
