That is a long article. What is your summary?
I get that his dad and the SEALS were important to him.
What did I miss?
I don't think I would offer you a true picture in trying to explain it. The author does a great job of drawing you into the story. I know he's quirky and a bit reclusive, but thinking of him sitting alone in a 40,000 sq ft gated mansion playing video games is a dismal picture.
I believe his life was destined for ruin before he was out of high school. When he was young and played in junior tournaments or at more exclusive golf courses; his dad could have said walk tall and show them who you are. Instead he told him, "They don't want you here."
