跌跌撞撞年少轻狂不再轻妄
[diē diē zhuàng zhuàng nián shăo qīng kuáng bù zài qīng wàng]
Indicates maturation and self-discovery. Initially filled with youthful exuberance and brashness (falling many times), there’s an acknowledgment of growing wiser by learning from past mistakes, thus no longer acting recklessly.
