Get your life organized. Prioritize your tasks throughout the day, the week and the month. Write down the top 25 things that you want to accomplish in your life. Circle your TOP 5 things that are the most important to you. Write those TOP 5 things on a separate piece of paper. These are the TOP 5 things that you are going to spend your days working on; only these.
Take the paper that has the other 20 items and fold it in half and put it in a safe box somewhere for keeping. Only focus on the TOP 5, don’t work on the other 20 things at all, but you will remember them. Remembering them will help you work harder on your TOP 5 most important things and get them accomplished.
