Because you’ll never be satisfied with how much money you earn

When you earned $20,000, you were very excited to get your first $2,000 raise.

When you earned $40,000, you wondered how long it would be until you earned $50,000.

When you earned $60,000, you wondered how you’d once survived on so little.

When you earned $80,000, you were very upset to learn that one of your colleagues earned $90,000.

Now that you earn $100,000, you’re finally ready to quit your job and go back down to zero.
