Some people seem to have low computer self-esteem. Being shown around my new workplace, several people introduced themselves as being "in the remedial class", "hopeless" or "the one who causes the problems". I just wonder how we got to that point. Why should people blame themselves for computer problems? Probably because programmers and sysadmins have spent years blaming them.

PS - You can stop blaming yourself now.
PPS - Well, maybe not for everything.
