This child came to us loud mouthed and aggressive. Once, I had to take him to task for using the word "F***!" He worked rather poorly in teams because he was easily frustrated. He has now matured into one of my most skilled leaders. We were able to temper his strong will from what it used to be: hard and brittle like an iron rod, into what it is now, pliable and yet strong, like a steel cord.
In school, he went from a boy with behavioural problems, to school prefect.
