Something that gets asked around is what is the best advice I ever received?
In my early years of metalworking I was involved in blacksmithing. Coal fired forges, making basic items, everyone wants to make a knife, so made a few knives. But there was this other older blacksmith. They called him Rainbow. I don't know why. He taught me a lot though, he was a very good teacher and very knowledgeable.
Others would come up as ask what I'm making, and I would tell them. One day Rainbow comes up to me, after someone asked what I'm making and I replied to them, and he says "Never tell anyone what you're making, because you might be making scrap metal."
That is 100% spot on and ever since I would only say what I intend to make. But I think the message applies for a lot more than just what are you hammering on the anvil. You make a weld tack because you know you might have to cut the weld to reposition the material and it's much easier to cut a tack than a full weld. Sort of hedging the bet on a possible screw up. You might say you're making lunch, but not specify you're making lunch for the dog because you screwed it up.
But I think the better message is of the humbleness of it. We can intend, we can try, but in the end we screwed up and have to start all over. And if you get big headed and proud that you know what's going to happen, you might end up realizing the whole time you were building scrap metal.
