Definition of perfection is the quality or state of being perfect, freedom from fault or defect, an exemplification of supreme excellence, the quality or state of being saintly. But in real, perfection is only an illusion. The only thing we can do, is our best. This is what we should go after. Every day, work smart, and when you go to sleep, check with yourself: “Did I do my best today?”. If so, congrats!
