If I were you, I'd buy a share in an aircraft and just enjoy flying.
On our refrigerator door is a sign "Get your kids into flying!!!. You'll never have to worry about them being able to afford drugs."
You have a share in six children, a house and a wife, and an ex.
More than enough to be getting on with.
Your goal should be get them a PPL at age 17.
The goal for you should be a flight instructors license.
