Hello Gentlemen!
This morning my wife brought up the subject of starting a new career. She works at a nice restaurant with with various positions and usually makes reasonable income.
She had previously gone to beauty school but decided against it (though she was excellent at it) halfway through.

Today she said she thinks maybe she might consider becoming an auto mechanic... And what do I think?

Well it seems as though no right answer short of full agreement could come out of my mouth.
"Well babe, if you really want to then you should do it. Let me tell you what I know: the work conditions can be a bit miserable, fairly low starting pay, it's hard on you body, and you'll be hanging out with dudes most the time."
This was an unacceptable answer. She was angry.
Where did I go wrong?

You guys have any suggestions on tact?
Any suggestions I could offer her as to a way she could explore better career options?

Most of you guys have a few years on me, and I'd be grateful for some advice.
I know this isn't a shave question, but outside work, I get a whole bunch of steady advice on many matters from this forum.
Thanks!
