And idk. My best friend from high school moved out here with me and he's a waiter making 40k a year and seems totally happy. Works like 30 hours a week, no mental stress, able to work out and work on himself. I think money is highly overrated.
But I think my main point is both of us have a way of becoming sustainable so you might as well do what makes you happy instead of working a job you hate for 8 years. Being a waiter making 40k isn't enough long term, but working your way into a higher end establishment or management is. A girl I dated started out as barista, became a store manager, and is now the regional manager and makes ~125k a year and more importantly she is a perfect fit for the job and enjoyed it the entire time.
All I'm trying to say is there are a lot of paths to a sustainable life even when following your natural inclinations.
But anyway OP responded his son's not super interested in college anyway so his plan sounds good to me anyway.
