Just do one little thing. Block away interruptions for just 15 minutes and knock it off. Just one thing. The world can wait. How were the pyramids built? One piece of stone at a time. How do Olympians win medals? One day of practice, one exercise, one repition at a time.
The world is full of distractions. The only way you are going to finish that to do list is to prioritize, and do the thing at the top.
