How Social Media Changes My Life
Every teenager has a story with social media—here is mine.

One possible version:
Social media helps me in many ways. I can chat with my friends easily. I watch fun videos to learn new things. Sometimes, I can find answers to my difficulties. But social media also causes me some problems. I spend too much time looking at my phone. It makes my eyes tired and I sleep late. Sometimes I even have no time to do my homework! So, I make one rule for myself:Stop using social media at 9 o'clock every night. I put my phone away. This helps me go to bed early and study better. Social media can help us, but we need to use it in the right way.
