On days when I tell my son to take an auto and save time instead of waiting for the bus and he says “No Maa, A penny saved is a penny earned”, I know he has matured. This is the very child of mine who would ask for a stuff without checking its price or whether its really required or not. Of course, he was much younger back then. Now, he he knows what is important or necessary or priority and what is just an impulsive buy! Of course, we do indulge him once in a while. But this lesson learnt will help him throughout his life.
