Yes. I view myself as a failure even though objectively if someone else had done what I've done in life, I would consider them reasonably accomplished.
I can't tell if I just have impossible standards for myself or if it's just a self esteem problem. I also think it's harder to appreciate an accomplishment when you know how messy it was getting there and saw the failures and stops and starts first hand. It's easier to appreciate something when you just see the finished product.
