Comparing yourself to someone else is always an exercise in futility because you have no frame of your reference to do so. You weren’t born on the same with this other person, and even if you were, you don’t have the same skills, abilities or experience compared to the person with whom you are comparing yourself.
More insidiously, comparing yourself to your former self is like trying to drive a car with the parking brakes on. You are not your past mistakes or successes. Those are gone. Today, you have a new opportunity and you have got to take this opportunity of a lifetime within the lifetime of the opportunity.
All comparison with others or your former self is a recipe for misery. Let go, and embrace today with a sense of becoming your best self yet. Have a great day!
