I worked on a farm every summer for over 10 years growing up. I absolutely hated every minute of it.Nothing wrong with garbage slinging and cement work.
My sons a cement man. He started learning the trade at about 13. Fast forward to 34 yrs old, he makes wayyyy more than probably many agents on this board and he's built like a brick shithouse. Makes more than I do bar none and close to what my hub makes. I will say though, he now has employees doing much of the hardest parts. It will tear up a body that's for sure.
I have many life clients who are blue collar workers and have mad respect for those guys.
Enjoy the week you get with your gdaughter. To me, theres nothing better than the love a gparent has for the gkids and vice versa.
My son is only 9 but has his grandpas' (both) proclivity for fixing things/physical labor. I think he'll make way more in doing a trade than he would in some corporate gig. I'm not pushing it, but giving him everything he needs to explore that route.
