He should've gone for his Masters if wanted more education and to reinvent himself. I've said that from the start.
His excuse was it was "cheaper" to do CADD but it was cheaper the same way flushing $1,000 down the toilet is cheaper than buying a $10,000 car.
Obviously, the real reason for CADD was so he could suspend having to look for a job for a year. We all know that. He obviously didn't excel at it. He just needed an excuse to sit around for a year without having to look for work.
He should have gone back to finish his computer science degree and worked as an IT guy who just sits in a computer room all day and occasionally fixes someone's computer problem. But I think CADD took longer, so he went for that.
