"他们说我冷静下来了，是的，之前我就是个活跃分子，一个坏孩子。现在，我想我没那么坏了。"

Simplified Meaning:

This quote is about someone reflecting on how they have changed over time. They used to be full of energy, causing trouble and getting into mischief, similar to a live wire that is difficult to control. Over time, they have become more settled and behave better, but still recognize that they are not perfect. Imagine a teenager who used to skip classes and get into arguments with teachers. They might have been grounded often for breaking rules at home. However, as they grow older, they start to follow the rules more, maybe focusing on schoolwork and helping out at home. They might still have moments where they push boundaries, but overall, they have made positive changes. Anyone can apply this idea by recognizing their growth and continuing to improve. It’s about acknowledging past mistakes and working on being a better person. You don’t have to be perfect, just aim to be better than you were before.
