This guy no longer talks about it simply and naively.

You find that you are no longer a simple change without you. You are so naive. Now you may have changed. I think it's normal. No matter how good or bad it is, it is also a change. No matter what problems we encounter, we must look forward. Change is a kind of growth for everyone, whether it is good or bad. You must face your change correctly. What is it like? I think maybe your essence hasn't changed. You're still that teenager. It's not that you want to be mature. Well, you think more problems and solutions have changed.
