Now I think, John Maxwell's life is a little more busy each day then mine. That's quite a list. I'd be tired at the end of the day. But I don't think he is telling us that we must do all of these things every day. He's telling us to decide in our heads and our hearts how we should handle each of these areas and then when they arise we can manage them properly.
In other words, make the decision once that you are going to have a positive attitude, that you are going to be a generous person, that you are going to try and grow and improve. You can settle an issue once and for all, and you won't have to revisit it daily. It will become a part of you.
That's a good idea for two reasons: it takes the emotion out of the decision and it makes managing your life easier.
