No matter what frustrating situation you are dealing with, getting outside of your head can help. I’m not talking about forgetting the frustration or distracting yourself, although that can help you get a break from the frustration and recharge so that you can think clearer (see the tip on where to put your focus below). But, I’m mostly talking about connecting with other people who have been where you are and have some ideas for you to use. Connecting with other people allows you to brainstorm for yourself.
Good is the enemy of great. And that is one of the key reasons why we have so little that becomes great. We don't have great schools, principally because we have good schools. We don't have great government, principally because we have good government. Few people attain great lives, in large part because it is just so easy to settle for a good life.
