There are a billion games that you can play in the world. In your wildest dreams, you won’t play even a tiny fraction of them.
Some of these games, though the fault of no one in particular, are rigged in favor of certain people and against others.
Since you can choose, by and large, which games to play – don’t play the ones that are rigged against you. Play fair when you can, and don’t cheat others. But there’s nothing wrong with just opting out of the games you can’t win.
This isn’t just “pick your battles.” This is also “don’t make your life harder than it has to be.” You’re going to have to play a few rigged games in your life. You’re going to have to fight a few battles where the odds aren’t in your favor. You’re going to lose some of those. So take your wins where you can, and play the games that are fun.
