i work towards prioritizing things that need the most attention. then delegate the leftover ones for the next day and make them a priority. like a rolling list of actions and if one thing doesnt get done repeatedly i look at if it was really all the important.
When I don't complete my to do list. I of course am unhappy with myself. But then I tell myself, hey that's in the past now. And then I start finding a place in my next day to complete the task.
