Videos like this typically annoy me, but I like ideas presented.

Specifically #3: Position over submission. Another way I like to think of this is, try to play a beautiful game of chess. To some, it's fun to play gambits and win early, but to me, it's more exciting to get all the way through an opening and no pieces were taken after 12-15 moves. Regardless, ensuring your position is never compromised, even for the sake of a quick win attempt, seems like it has applications all throughout life.

One of my favorite chess mental models wasn't actually mentioned in this video, and it's called "asking the opponent a question". A very basic example is below - white wants to challenge black's ability to fight for the center by going Bg5, threatening to pin the knight if black were to play e5.

In lower levels, black often plays Nbd7 trying to immediately defend the knight, so that if bishop takes, the typical king side structure for this opening remains in tact. More aggressive players also like to respond with a pin of their own

But the best move for black in position below is to "ask a question" by simply playing h6. White can respond with Bh4 if they wish to maintain the threat, and from there black can either decide to trap the bishop completely with "... g5, Bg3 Nh5", or black can lose a tempo by playing the best move, which is retreating the bishop to f4. But a highly instinctual way for white to respond, especially in lower levels, is to justify the threat by taking the knight, even though this loses the dark squared bishop against a fianchetto'd opening.

Asking a question is very similar to the "just slowly develop your pieces" mentality, which I briefly mentioned here: #571772

This is especially helpful when you're playing against aggressive players and gambits, which happens often as you're first learning to play chess. The tendency is to respond with counter gambits and memorize tricky lines, and while there's nothing wrong with that, you have to be VERY accurately and somewhat counterintuitively, which may not be as rewarding to your ELO in the long run. In my opinion, slowly developing and maintaining an even position is not only a more respectful way to play, but you often find that opponents who are attempting to catch you in an easy trap tend to over extend and fall apart. Of course it doesn't always work that way, this isn't a "get ELO quick" scheme, but patiently and humbly learning the principles is how you become solid in strategy and character over time. It's the chess version of "stay humble, stack sats".

"Don't rush, slowly develop your pieces, play the long game" has so many applications in life and relationships. Build integrity. Be respectful.

Lastly, here's a fun piece of life advice that has applies beautifully to chess: "instead of defining yourself by your ability to reason, define yourself by your willingness to learn" (from the video posted here: #474595

In chess, you could say "instead of defining yourself by your ability to win games, define yourself by your willingness to learn from every game".
