It's funny it feels like a 'downgrade' as it is more lucrative. It is also really fun. You feel like a superhero when you show up at peoples house and rescue them from their problem (which if you are a plumber is often serious). I also noticed that we did a fair bit of almost counseling when we showed up at peoples houses, which also felt great. It got me out of the house and meeting people. To me it seems like a good noble career.

And let's not forget what Einstein said.. "If I would be a young man again and had to decide how to make my living, I would not try to become a scientist or scholar or teacher. I would rather choose to be a plumber or a peddler in the hope to find that modest degree of independence still available under present circumstances."
