No one lives long enough to learn everything they need to learn starting from scratch. To be successful, we absolutely, positively have to find people who have already paid the price to learn the things that we need to learn to achieve our goals.
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.
