Stever Robbins said this quote
“ Asking why you are doing something serves as a check and always moves your focus back to the big picture. Asking why helps you find out if your actions have come unglued from your goals. In theory, you could do this as often as every day, reviewing your to-do list to make sure it ties to your bigger goals. In my perfect fantasy world, I check my actions against my goals every day. In real life, once a week or once every other week is more realistic. ”
