Yeah, that pretty much sums it up.
While I agree that it is a good idea to be a little easier on myself, I tend to try to err on the side of being hard on myself -- because, frankly, it seems optimal (har) to me to be just slightly harder on myself than any reasonable person. Being less hard on myself than a reasonable person makes me more prone to inexcusable error somewhere along the line.
I also feel like I have a bit of a duty to be harder on myself than on others. Better that than hypocrisy.
