Phil Cooke said this quote
“ Be ruthless in one important area: Yourself. Be ruthless about your commitment to Christ. Be ruthless about your intellectual growth. Be ruthless about finishing well. One of the biggest areas we should be ruthless about is our time. How much time do you spend complaining about your problems to people who can't help you solve them? How much time do you talk when you should be doing? When it comes to others, be gracious. But when it comes to you and your time, be ruthless. ”
