Here's the thing, though: if you see an apprentice carpenter screwing up, how do you help him? The only think I can think of is to try to explain to him how to use the tools. Seems to me like that's better than telling him, "Sorry, you have to figure it out on your own."
I like this analogy.
There are good carpenters and there are bad carpenters. Not all good carpenters do things the same way, but there is some commonality. Two good carpenters might argue about how best to build a house, but each will build a solid house in their own way, using the tools they've learned.
I'm a very inexperienced carpenter. My dad was not very handy, he taught me how to make enough money to pay someone to fix your house for me. I'm a little more handy than that, but I acknowledge my inexperience, so, my brother in law helps me with home repairs. He bought this oscillating saw, amazing for doing small precision cuts! I would have used the reciprocating saw, which is good for rough cutting. He's got a ton of little techniques that make the work go well, the end result looks good. He's finished his own bathroom and done a lot of that kind of work.
I do the same thing when a new programmer is trying to write software. I show them "the ropes", how not to write shoddy software. Other software developers may disagree with my exact methods, but if they've also been at it for 20 years, we'll agree on *some* things, at the very least that one should follow *some* methods and guidelines. The problem with the young guys is they don't yet know which rules should be broken and when, so it is safer just to tell them to follow "the rules" knowing that you don't have all the answers. But, you have some answers, and they work well enough.
When people come into a craft, there are varying degrees of skill people have learned, varying degrees of awareness of the complexity of details that will need to be learned. Some people can figure out much of this on their own, just by watching other carpenters. Some people need to be told that the nails with the heads on the wrong end aren't for the other side of the house, you can actually turn them around. Some people can only learn by building shoddy houses and then having an expert point out the weaknesses.
