Family comes first, don’t jeopardize them by chasing a dream. If your wife is able to work full time, you could probably make it happen but your kids will suffer and eventually resent you for it.
Plan for the future and set your kids’ up for opportunities instead. Maybe one of them can become a pilot. You would feel far more pride and joy if they made it instead of you selfishly chasing your seethe simmer dream.
