"In school, you learn that there’s symmetry in the world. Every force has an equal and opposite reaction. Chemical equations must balance. Supply and demand are intimately related. Life is no different. It’s full of tradeoffs and cause and effect relationships. You’ll never get something for nothing. Everything has a price. First you do the work, then you get rewarded. You give, then you get. Those equations appear throughout your career, your life, the business world, everything."
