Often when we overload ourselves with activities we get overwhelmed, we don't know where to begin. The problem is, most of us keep activities on our mental activity list. So get it out of your head! Do an exercise right now. On a blank piece of paper write down everything that you need to do. Then go back and ask your self this question with each activity you wrote down. "What is the next action" and write it down next to the activity. This will give you a clear picture of what to do.
