In times past, initiative and perseverance were characteristics parents actively promoted. parents thought twice before doing things for young people that the youngsters could do for themselves.
We can promote initiative and perseverance, which are part and parcel of responsibility, by asking ourselves, "If I do this for the youngster when I know that the youngster is capable, will I be depriving that person of an opportunity for growth?"
If YOU want to grow, do it YOURSELF.
If you want the other people to grow, don't do those things for them that they can do themselves.
