If we choose an external marker as the measure of our inner worth, whether it is the amount of money we make, or others' opinion of us, or the success of some project we're involved in, sooner or later we're bound to be battered by life's inevitable changes. After all, money comes and goes, and thus is an unstable source of self-esteem, an unreliable foundation upon which to build our identity.
Dalai LamaThere is no way to escape death, it is just like trying to escape by four great mountains touching sky. There is no escape from these four mountains of birth, old age, sickness and death.
