LPT Request: "Getting creative" when not around others

When i'm around others, there is always a lot of discussions evolving around all kinds of topics. To me, these are valuable moments of insight and we have a great time laughing and my mind is racing. But when I'm alone, i feel like i should be writing, or rather "should want to be writing" to channel my creative energy or whatever you wanna call it and come up with "ideas" or insights that are comparable with what i experience when around others.

I'm searching for a way which triggers "this kind of thinking" without having to depend on others to interact with. Documentation also would be really hard, i can't run around with a microphone. I have a .txt with ideas, but theres not as much going on in there as i'd like.
