My biggest tip would be one of two things: first of all, consume. Listen, read. Just consume content on a regular basis. Start to spend 5-10 minutes once or twice a day. Just go through your feed. Read some articles and posts. Watch some videos. Consume. Listen to what people are saying and how they are saying it.
That will help you A, get you used to how people are creating content, and B, give you ideas about what you might want to say. And that’s one of the ways that I come up with ideas. I’ll pick up a book and read a couple of chapters or watch a video on YouTube, or I’ll listen to a podcast. Listen and consume regularly. The other thing you can do is practice. Practice makes perfect.
