We use the term 'Prioritize and Execute' at the shop all the time. It's from Jocko's Laws of Combat. Find the priority and execute. Once complete, there's a new priority. Then you handle that.

This is the antidote for overwhelm.

It's easy to get bogged down with the big picture of getting everything done. You can't do it all at once. Take a step back to detach. That'll help you find the next step you need to take.

This can be applied to all aspects of life. When you're feeling overwhelmed, detach, identify the priority, and run the play. Before you know it, you'll be moving forward. Forward movement generates momentum. Now you're off to the races.
