"The secret of your success is found in your daily routine."
You will never change your life until you change something you do daily. The secret of your success is found in your daily routine. So any system you develop needs to promote consistency, and you must follow it consistently.
What does it take to develop consistency? A system and the discipline to follow through. I came across the story of an older gentleman at the funeral of fiery NBA basketball coach Bill Musselman in 2000 who approached Bill's son Eric to tell him a story. The gentleman said he was driving down a two-lane highway on the way to Orville, Ohio when he saw a boy about elven years old dribbling a basketball with his right hand along the side of the road. The man said he pulled over and asked the boy, "Where are you going?"
Without stopping dribbling, the boy replied, "Orville."
"Do you know Orville is ten miles away?" he asked.
"What are you going to do when you get there?"
"Dribble back with my left hand."
The old man looked at Eric and said, "That boy was your father."
Now that's what I call creating a system and having the discipline to follow through on it.
