Why can’t you upset the balance if you believe (based on your own observations and your son’s life skills) that your H is wrong? To me, this is a balance worth upsetting.
There are workarounds, skills your son can learn, organizational tools that others with brains like his have used to minimize the stress that goes with taking twice or three times as long as other people to accomplish a task. And a good coach can also bring out the strengths– whether it’s creativity, energy, the ability to see patterns that other people miss– EF coaching isn’t just for deficits, it’s for identifying what he’s really good at.
