We are strange animals: part for ‘nature’ part for culture we learn through an action-reaction mechanism.
It’s all about feedback, it’s all about consequences: we do something, something happens due to what we do (or don’t do), we see these consequences and decide what to do.
Do you want to mess up a team, or your son, or a person you have a relationship with? Start not giving feedback or better giving random one: the consequence are certain … #fail
p.s. Please note that sometimes not giving feedback deliberately is a feedback itself (remember: you cannot not communicate)
