I never thought I was anxious, but my sister pointed out I have structured my life to an unusual degree to avoid stimuli that could create anxiety: I don't drive, I worked from home my entire career even before it was cool and at a dev job at a company of the ideal size to allow me to avoid office politics or excessive meetings, I spend most my time reading alone, my life is highly routine, I often eat the same foods day after day until I tire and move on to the next thing, and I travel rarely. 

I have no idea if she is right or not. And if true, I am unsure if it matters if such things grant me some peace. But the idea that the shape of one's life may be, in part, an unconscious treatment for mental flaws is a disquieting one. And it may be worth asking yourself: looking at the structure of my life, what symptoms might I be unconsciously treating?
