You should be doing this everyday, but maybe you aren’t.
There could be simple reasons for not thanking people. You don’t think you need to, you think the person knows you appreciate them anyway, you think people will think its fake, or you just don’t think about thanking!
Today, thank everybody!
Thank everybody who does anything for you. Thank the bus driver, thank the cleaner, thank the laundry man, thank the security guard, thank your support departments, thank your customers.
