Every morning when I was a child, my father would bound up the stairs and at the top he would say (without fail) “YES! Today is going to be a GREAT DAY!” That used to drive me crazy. Now, I get it.
See, my Dad had a reason to believe it would be a great day – he knew it to be true because he had a clearly defined purpose for his day, his week, his month, his year AND his life! In other words, he knew exactly WHY he did what he did.
