Most people measure their self-worth by the size of their bank account.
The bigger it is, the better they feel about themselves. Because we put so much energy into earning money, it represents the very energy of life as we see it. Some people feel that they and they alone are responsible for their success, that their intelligence and abilities made it so. And you must do everything possible to ensure success, not just sit back and wait for money to come your way. But you must acknowledge that it is G-d's blessing, and not your effort alone, that creates wealth.
