I'm grateful for everyone in my life that has ever said "You know, you COULD try that, but it's a bad idea and let me tell you why."
Absolutely true. Still, blundering but persevering means that a would-be mechanic is likely to learn not only how to fix something but also why that method is best.
That said: ". . . . and let me tell you why" - I wish I'd done that more often when I was running service departments in bike stores.
