Sometimes I wonder when should I send a thank you. And should I send it via snail mail or email, or is a verbal thank you good enough? According to Ann Marie Sabath, author of One Minute Manners, anytime someone exerts more than 15 minutes of energy to do something for you a written or keyed thank you is in order.
So the next time a colleague helps you meet a deadline, or takes you out to lunch, send that person a thank you note. Ms. Sabath strongly encourages notes by snail mail rather than by email. She compares thank you emails to getting a hug without being touched. On the other hand, a snail mailed thank you shows the thanks was premeditated and not impromptu. So consider mailing a thank you note to someone that helped you out. I know that when I receive a written thank you it sure brightens my day!
