We often her about how someone is a natural athlete which odd since science has proven repeatedly that doesn't exist. I sometimes her about how two players should be put on team together because they were on the same school team, club teams, and they had the same coaches. This logic is usually motivated by folks that are uniformed, or are just being to hyper about their child's self esteem, or how the family looks. No two kids will have the same amount of benefit from a coach, it's not possible. Its not the coaches fault it's the fact that the kids are individuals that causes this. Two brother from the same family can me very close together in age but yet have totally different perceptions of life growing up. The point being is that no one can account for what a player was thinking. Most of the kids are hearing identical messages 90% of the time, but in the end one will have improved more because they made better use of their own thoughts. Two kids can be set the same slight out of position ball. Player A thinks about how to handle the bad situation better next time and Player B is thinking about how it's the setter fault. Learning from feedback and learning from mistakes makes all the difference. A growth minds set can helps players be much more productive.
