When people are feeling negative emotions (e.g. due to depression, anxiety, or relationship problems), their thinking becomes more negative, narrow, and rigid.
People tend to get very “all or nothing” and “black and white.”
Achieving greater flexibility in your thinking will help you claw out of the psychological hole of suffering that you are in.
One way to do this is to be on the look out for (and take) opportunities to get “some of what you want” when the option of getting all of what you want isn’t available.
