Wow - I dont trade for a living (thankfully) but if i did, I couldn't tell my mom either. She'd freak. I think i'd tell her that I was working as a male stripper (at least then i could tell her that I get benefits)
Newly, my Dad always cautioned against the stock market too - called it a casino - and that was advice from decades ago. How much more of a casino it's become!
I'd be much better off had I never 'invested' (and I use the term loosely) one thin dime.
