I don't mean (touch wood) catastrophic end of the world errors that cause millions of pounds to fix. I mean things like typos, perhaps forgetting the odd thing, not double checking things and filling out forms and occasionally making errors like getting a date of birth or something wrong. So nothing that ruins anybody's life or anything but things that might need to be corrected now and then, things that other people aren't usually that affected by... but things you feel so embarrassed about and beat yourself up over? Even in senior roles?
I worry about these things ALL the time. When I look back I've spent so many weekends fretting about things like this and it hasn't even happened or has only taken a quick tweak that other people don't seem to beat themselves up over.
It always seems like everyone else is perfect as well!
