I transform overwhelm into major accomplishments.
For many overwhelm comes from trying to get a lot of things done at the exact same moment. The feeling can be very intense which means you are passionate and invested about the task itself or the outcome of that task once accomplished.
So, take that energy and transform it into a list of everything you are wanting to accomplish, put them in order of priority to be completed, and then check them off one at a time as they are accomplished. Do not stay overwhelmed, let's transform it into accomplished.
