Great article. I admit I get anxious in certain situations, like when my car was stolen and wrecked recently, but I do tend to get over it quickly.
Like you though, I don’t seem to have spikes of emotion. My wife says nothing really gets me super excited, unlike her, and I am sure she is right. Things happen, good or bad, and you go with the flow. If something good happens great, celebrate it, but don’t overdo it … that’s me.
