Only the one who finds himself in a duel in a stronger category knows how difficult it is to fight.
He is a winner among older and stronger children... That gives victory even more value!
I remember my childhood, when I tried football. I was late to be in the youngest category, so as a beginner they transferred me to a stronger category (two years older than me).
I didn't last long. Football is still a contact sport, which I couldn't stand, I was too short (I'm not too tall even now, but I was really tiny at the age of 8).
Being challenged with difficult things can be a great way of finding ones limits...and pushing past them.
