I admit that "Save Early, Save Often, Don't Overwrite Saves" would have actually been useful to me as a kid. Not in playing Sierra games, because I didn't grow up with them, but other games like the Nancy Drew series. I can still remember the very first time I ever got stuck in an unwinnable situation: it was a game called Mystery at Rosemond Valley. A spinoff from the Lets Ride! games I enjoyed as a kid, it was unique because it had nothing to do with horses whatsoever (hence the "Lets Ride!" title), and instead of starring Annie from the Rosemond Hill game, it starred her sister, Emma, who was a journalist who was on the case for some stolen diamonds from a museum. Said unwinnable situation was because I didn't know to show an old lady a photograph that I'd found in the attic to continue talking to her and get extra info for the case. As soon as you exit that house, you cannot go back in as the text says "No answer. Maybe she's sleeping."
Another example, just due to own stupidity was Nancy Drew: Danger On Deception Island. I misidentified the piece of wood I found, and I couldn't call up the person who identified it again, which got me stuck later on. I feel said dumbness because when I was looking at it closely, I could see that it was reddish brown, not brown brown... and yet I still said it was the latter anyway.
This is why I like stuff like Let's Plays and using walkthroughs. I don't care if it's seen as cheating or weak, I hate getting stuck, dammit! Heck, I've been introduced to so many game series through LPs, when otherwise I wouldn't have given them a second glance in the store.
