My oldest is going to college this August. My youngest will be going in two years. That will put me at 46 when they are both out and hopefully around 51 when everyone is done. That said, both are very interested in things that will require more school after their bachelor’s(law and bio) if they maintain the same interests.
I am thinking, worst case, they should both be out of all school and far enough into their careers to be stable by the time I am 53-55.
I might sell my biz and just build decks or something then. Just me and one other guy, just easy simple decks, and just one at a time. Take winter off and chase the Tangcats to away games.
