It is well known that the three major characteristics for which people are praised in this world are: wisdom, strength and wealth.

Wisdom is the most secure of these, for it resides within a person’s soul.  Moreover, one’s wisdom generally increases with age.

Strength is next, for it resides within a person’s body.  However, as a person grows older, his strength generally lessens.

Wealth is the least secure, for it is external. ~ Rabbeinu Yonah of Gerondi zt”l
