Any theater of life, a family, company or school, where people know how to say thank you, and do so on a daily basis, is a better one. It spreads like a cold.
Thank people for their time, their effort and their attention. Thank people for listening, for showing up, for waiting for you when you are late. Thank people who you buy services from, thank people for wanting to buy what you make, thank them for caring.
Thanks for the coffee, thanks for the feedback, the debate, the constructive argument, thanks for bluntly telling me what you really think.
