I found this quote today; like it I do. I can relate completely.
"Tension is who you think you should be. Relaxation is who you are."
I run around tense most of the time. Why? Because if I'm doing little, I think I should be doing something productive and if I'm doing something, I think it should be a bit better.
Conversely, when I lose myself in something (like playing Scrabble last night with my husband and daughter over a bottle of wine), I am relaxed. Was it the losing myself in who I am or was it the wine? I constantly second guess my success.
I need to work on this. A lot.
