I’d like to ask the good people of this community that, if you do know the solution or figure it out, that you not share the answer here. Feel free to announce your success, but there’s something to be said for discovering the answer completely unaided, even if it takes years.
It’s embarrassingly obvious once you see it though.
Yes, the hint that the answer was obvious once you knew it was extremely helpful.
I’m not that quick with math, so knowing that the answer was going to be simple helped a lot. Every time I had an idea that was too complicated, I shelved it and kept looking for something that might be simpler.
It also helped that I was a camp counselor, and one of our survival techniques was to have riddles with simple rules that the counselors were able to operate very easily, but which the kids used lots of brain power to try to figure out.
