Rewards, punishments, and telling just don't work for far too many of them. Rewards motivate young people to be responsible. In addition, we are not honest with young people when we give them rewards for expected behavior. Society does not give such rewards. Punishments are necessary to change young people's behavior.
Punishments satisfy the punisher but have little lasting effect on the punished .
Once the punishment is over, the person has served the time and has relinquished responsibility. Young people need to be constantly told what to do. If telling worked, you would not have to repeat yourself. Young people want to be responsible, but we are using wrong approaches to help them. People who use the strategy find it life-changing.
