Well, think of it like this, underneath the coveralls and hard hat, if you have a bad hair day, no one will know!
80+ hours/week is a LOT, but if you're getting time and a half for overtime, those paychecks will sure look good! Big change from fast food, that's for sure!
Even if you aren't getting time and a half, those hours still pay off. That, and a job you really LIKE? It's a beautiful thing!
(Can you get the coveralls in a nice color?)
