We always said he should be a political analyst.
You know I do not know what is your son's disability but a very famous political analyst writer, the most highly regarded in the country I think, or nearly so and surely the most brilliant was named Charles Krautheimer. When he was in medical school, I think it was then, he had a diving accident and became paraplegic. He finished school somehow and he became a psychiatrist.
Eventually he entered journalism, both print and TV. He was affiliated with Fox News.
He married and had children. And had the most fulfilled of lives, it seems.
I do not know what his family background was.
In this day and age with the availability of communication mediums, like blogs and podcasts and self-publishing, there is really no limit in how one decides to define themselves in terms of the spoken or written word.
Nor are there significant limits in terms of education. Not only is there one to one assistance provided in physical classrooms, in the form of aides and whatever adaptive supports are required, there are online universities through the Phd. I am taking two courses online now. In one at a rabbinical college everybody in the class meets on zoom. The other is a foreign language course that meets entirely online.
I have taken studio art classes online.
The Department of Rehabilitation would potentially pay all costs for school if he wanted this. They would probably pay for and support him for any goal he had that was reasonable. Particularly if he had a advocate to help him through the process.
Your son seems like he is living a very fulfilling life. He sounds content with himself which is everything. I am not saying that he should not aspire and attain, but it sounds like he has a strong base of friendships, support, strong interests, and most importantly, healthy self-regard. You must be extremely proud of him.
