The mind is funny. When given a puzzle that you can't unravel, it goes crazy thinking about it.
But here's the thing -- with a little bit of practice, you can start to say, "Hey, all the possible roads this puzzle unlocks are actually pretty useless."
A lot of times you'll come across something confusing and want to make sense of it. But as soon as you realize that there's no profit in making sense of that particular item, move on promptly. There's plenty of puzzles that are interesting, enjoyable, and profitable to solve.
