Consider the list. Was this person an upbeat coach? Did he push you to overcome yourself and was, accordingly, aimed at a positive result? More often than not, the best coaches are models of toughness out of mercy. We understand that they invest in us, believe in our potential and strive for our success. Their faith in us is not expressed in a stream of nauseatingly enthusiastic epithets. On the contrary, they make fun of us, pressure us, mock us so that we overcome, overcome and once again overcome the existing barriers. We are trying our best to reach the level that they consider successful for us.
