I suggest young people experience betrayal and being framed before they turn 25, giving their all and getting dumped a few times. The earlier you experience these things, the less you'll lose. Once you see through the dark side of human nature, your mindset after 25 will be invincible. You won't care about encountering any seamless transitions or selfish oddballs. Youth needs to be toughened up by society, your naivety, kindness, and idealism will be shattered, and you'll know what reality is. All the道理 (principles/truths) are useless; you'll learn your lesson after being badly hurt once. I'm not advocating suffering losses, but experiencing hardship, losses, betrayal, deception, and being framed early will make your mindset and wisdom much stronger.
