No I don't worry as DH is rather savvy and houses will always need building. 'Bricks and mortar' and all that.
Have you thought to get passionate about a project yourself other than relaxing the day away or getting your hair removal treatment?
It doesn’t sound as though you know much about your husband’s business with that response about bricks and mortar - sounds a little flippant.
The most accomplished, interesting and intelligent women have something that lights them up. I’m not really getting this from your responses OP. I only made it half-way through was fairly repetitive and predictable. Sorry, OP. Best of luck hope you enjoy life to the full.
