Rob's father walked out when he was 14, so he grew up figuring everything out on his own. Now he makes the videos he wishes he had back then: how to tie a tie, change a tire, unclog a drain, be a decent person. Millions of kids growing up without a dad call him Dad.
He turned the worst thing that happened to him into a lifeline for other people's kids. If that is not the whole mission, nothing is.
