For what it’s worth, I’m not 40 yet and employed at a job where I’ve been promoted 3 times over 10+ years; I can step outside of myself to see what is happening to other people, though. My situation is fine, though there are people everywhere less blessed/driven/whatever.
Well, it seems you did say "the jobs we used to work ... " so regardless of the fact you've been employed for >10 years and gotten three promotions, you write like it doesn't sound as though you have much to look forward to.
I went into business for myself in my late 30's (BTW, my career is in pharmaceutical development, not AMWAY) and I'm celebrating 15 years in business this year.
I've held all the titles and had the the promotions, but I'd rather have the return business. I'd never look back.
If you're in your late 30's yourself and expecting to be on the street by 50, you might want to start making a plan to start addressing that eventuality now.
FReegards!
