The clearer you are about the consequences of your actions and the more intensely you desire to enjoy the consequences that your behaviors may lead to, the more motivated you will be.
Your success in life and work will be determined by the kinds of habits that you develop over time. The habit of setting priorities, overcoming procrastination, and getting on with your most important task is a mental and physical skill. As such, this habit is learnable through practice and repetition, over and over again, until it locks into your subsconscious mind and becomes a permanent part of your behaviour.
