Summarizing life philosophies succinctly is a good idea. Here are some impactful beliefs I've collected over the years: the fastest way to get rich is to go slow, many beliefs are held for social and tribal benefit, success caused by luck can blind us, social media is mainly a platform for performance, comedy is a great way to teach about human behavior, wealth is measured by what you have minus what you want, and not needing to impress anyone is the most valuable personal finance asset.
If you can explain something important in just a few words, it's a double win: You've probably found something that's obviously true, without needing further explanation or detail. And it's probably something you'll remember for a long time, easy to recall without having to memorize dozens of details.
This podcast is a smattering of ideas that have been important and impactful to me, shared in as few words as I can manage.
