The first step is being willing to move forward even though you may be afraid. The second step is saying out loud what is true. I hate my partner, I hate what I do, I am sad that my dog died or I want to move somewhere warm. Then you are free to begin to take action. It is not enough to just say, I envision a new wonderful job.
At this point, you can breathe deeply into the emotion and then begin to do what you really want to do.
Healthy emotions have a life span of 90 seconds. Don't hang onto yours.
