Everyday before the work day starts, take a few minutes to breathe. Clear your mind and then focus on doing what needs to get done that day. Many things will pop up in your mind. From that mental list of things write down three most important things to do on a piece of paper. Then aim to get only those three things done and try to avoid any distractions while getting those done.
That’s it. It’s best way I’ve found of beating procrastination.
