You might have ideas, but don't write them down because you don't think they're profound enough (yet). In that case, I'd suggest to track those ideas in an app or book. This gives you something to play with and reflect on, find patterns. If you actually have few ideas. then that is also fine. Why do you think you need ideas? You can think about or work on other people's ideas.
