Yea Dan, awesome. Got a bit semi-mental myself reading your post.
It doesn't have to be your kid or grandkid. Just take a kid or two fishing. I took a bunch a while back. They beat me to the fishing while I was cleaning up from breakfast. After I finally found them, they confessed that they had caught nothing. I showed them what to use, and how to use it. They began catching fish. Made me feel smart. Made them smile. But deeper than that, it just made me feel good.
Doing something like this puts you in touch with what we are here to do. We should be teaching those younger than us how to live. We should be creating experiences for them that attract them away from the negative influences and toward the positive.
