I admit I can't shake the idea that there is virtue in suffering that there is a sort of psychic economy whereby if you embrace success happiness and comfort these things have to be paid for.
I've always been too hard on myself to behave like I've arrived or even to enjoy whatever success I've had. I've always envisioned myself higher than where I was and I still do. With each success I think 'That's nice but I'm supposed to go there!'
