I too am a somewhat negative thinker….but only because he who fails to plan, plans to fail. When I go on Amazon to make a purchase I first look at the 1 and 2 star reviews; that’s the kind of guy I am - I always look for the worst instead of the best.
My wife calls me Mr Positively Negative.
I am a worrier and instead of making excuses for it or trying to change my ways, I’ve come to accept what I am. So when I feel doom approaching I laugh at myself, tell myself it’s just business as usual and embrace it.
You just cannot fight the way you’re made!
