This is the thing that's really hard to teach. I learned while finding an excellent lakeside kissing spot while driving my mom's brand new car. I buried that new 70 Fairlane up to the axle. It had to come out. I spent the whole rest of that date using the jack, trees, gravel and blood to get it up on dry dirt. Being good at anything is almost determinable by how determined, committed and willing to learn someone is. I think the best way to learn is hang with that kind of people and pay attention. Having said that, I've known some real eager young guys and it's a joy to watch them absorb abstract mindsets that you've developed over the years. For instance, when you enter an equpment/machine room it's good to learn to listen and smell for certain noises and odors that can tell you as much as a gauge. Millions of things like that are just the tools of the trade. But overall? Yeah...I get your gist.
