Negative thinking robs you of happiness and can be persistent. Here’s the ABCDE of breaking the pattern: A. Adversity, what triggered it? I failed. B. Belief that underpins it? I’m rubbish. C. Consequence of the thought? I’m miserable. D. Debate the evidence I only failed this one. I succeed at lots. E. Effect of a new way of thinking? I’ll try again. Challenge your thinking often enough and your brain will give up and start being positive!
