This is relatively good advice for a lot of levels of chess. But eventually, you might reach a level of chess where just not blundering massively isn’t enough to win - at some point you’ll need to learn how to make plans and put pressure on your opponent. If you do this well, you’ll pressure your opponent into making the mistake you’re waiting for!
It’s a lot easier to attack in chess than to defend. Learn to attack well (but patiently) and your elo will skyrocket
Don't try to win the game. How foolish that would be!
No! All you need to do is not lose the game.
When you play, just avoid blunders and mistakes. No gambits, no tricks, no aggressive play just for the sake of being aggressive.
A perfect game of chess is always going to be a draw. Just let your opponent make a mistake and capitalise on it.
Chess is a defensive game where you can't force a win, you can just play without mistakes or at least less mistakes than whoever you're playing.
