As a person who have worked in administration field, have you ever made a mistake and learned from it? what was it? share your experience.

We are all humans, so mistakes are a possibility

I've done minor mistakes which could be recovered and recorrected without losses, once i sent email to a wrong company and next day i was expecting response because matter was urgent when i didn't receive reply, i rechecked my outgoing email box to find that email was sent to wtrong email address, so i did correct and resend

I learnt that i must be more accurate and take enough time to ensure that all information are correct
