I recently heard this great piece of advice given about dealing with feeling overwhelmed with all the things to do with modern life.
Essentially they said to put everything you can actually do something about into one imaginary circle, and then put everything that you cannot presently do anything about into another circle. Then just concern yourself with the circle of things that you can do something about.
This is great advice because it helps you to to laser in and focus your attention only on what you can do something about. And then it prompts you to get moving into action, which is so much more effective than sitting around, getting overwhelmed by all of the things.
