Have you even bothered to google "fail forward D&D" to find out ways to use that method with the game?
How do you think I found the example?
An example that did sort of make sense to me (which I thought I mentioned long, long ago) was a character trying to knock down a crumbling wall. They fail their check and break down the wall but take some damage and are buried under rubble. Something I could see using but doesn't exactly apply all that broadly. https://www.dndbeyond.com/posts/408...g-without-ending-the-campaign#failing-forward. The reason it worked for me was because the result was a direct in-world result of the action. Most of the results I found were just more examples from other systems and vague.
