We back off. Now we are developing a no-go area. We could be developing a phobia. The answer is to ACT a little more and analyse a little less - so you don't get into paralysis by analysis. Too much thinking about the threats simply produces too much adrenaline.
Action dissipates both adrenaline and physical tension.
It also ensures that we increase our confidence rather than develop no-go areas. Decide to become more action-oriented. Do it rather than brood over it. And remain aware that the alternative is hours, days or even months of paralysis by analysis and the stress that goes with that and the way in which this ever-present stress saps vitality, saps the joy of living, and clouds each day. Start noticing areas where you freeze or procrastinate through too much thinking and analysing.
