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.

Better yet understand that none of your gear makes heat, you do. Think of your sleeping bag and clothes as batteries that need to be recharged periodically and your body is a generator. When you shiver that is your body trying to burn calories to produce heat. You can stay much warmer by keeping busy and moving around than you will by standing around a fire. When you wake up cold in the middle of the night, move your legs like you’re riding a bicycle while laying on your side. It won’t take long to warm up. Also keep an isolating layer between you and the ground like a foam sleeping pad. It also works for when standing on frozen ground.
