It’s none of your competitors. It’s your ego. That voice that says you know what you are doing, you don’t need to do it different, and justifies your actions. It’s that voice that says “You’re the man”, or “I can’t” or “I’m afraid to change”. “It’s that voice that says “If I just work harder, it will all work out one day” or “Nobody can do this job as well as I can”.
Your world will not get better until you do.
Are you better than you were last year? (For the answer ask, “Am I getting better results?”)
