We caught ourselves not teaching enough skills to our sons. Too often we would just fix something ourselves because it was easier than taking the time to teach. That was a big mistake. We ended up paying for our eldest son to take two classes taught by a plumber friend of ours that taught how to change the oil, and tires, and a few other things on a car, how to do maintenance on a lawn mower. how to install a sink and a faucet. How to install a light switch and a light fixture. How to repair and install drywall. How to maintain a bicycle, and a bunch more. Half of it we could have taught him if we'd only taken the time.
We did better on household chores like laundry, cooking, cleaning, money management, etc.
We definitely need to be intentional on training our kids and take the extra time to train them, even if that is watching a youtube video to figure our how to do something we don't know how to do.
