Let me ask you a question. What do you do when you want your car to perform its best? You keep the exterior and interior spiffy. You change the oil regularly. You make sure that all the required maintenance gets done. In other words, you take care of your car.
Why should you be any different? If you really want to succeed on your journey to earn more by working less—if you really want to perform your best—you’re going to have to take care of yourself.
