Maybe something you learned the hard way, or something you found out right before making a huge mistake.
E.g., for audiophiles: don’t buy subwoofers from speaker companies, and don’t buy speakers from subwoofer companies.

Do you have any good learning resources for number 4?
That depends on exactly what you are looking for and what level of play you are at. A general source that I do like for these sorts of topics is Chess-Networks series “Beginner to Chess Master”. I think its well put together and easy to understand/digest for beginners. Its free (youtube) which is also nice. Of course you can find many more like these on youtube. I just like Chess-Network for this type of series a lot.
