Overwhelmed? Do not know where to start?
Get a notebook and a pen and shut off your phone and computer. Get away for the office. Make a list of all that is on your mind. Keep writing and thinking. Then put them in 3 categories, maybe by putting a different notation next to each. Do-Delegate-Discuss are the 3 categories. Those that ONLY you can DO, those that you should DELEGATE, those that it is best to discuss with someone. Then begin to Do Delegate and Discuss.
