My best

What am I always telling Ben to do? Persevere!  He is starting to get it.

My highly sensitive boy used to just give up, but I see more and more determination and perseverance.  When some children get frustrated,  they've learned to keep it inside.   Ben, well, it takes him longer and he is so hard on himself.  

If I have one word I want him to remember I helped him personify, it would be perseverance.  

He is getting it, one day at a time.
