If you haven't already, joining other creator or janitor servers to find fun collabs is one thing that helps as it alot! There are plenty of these during the holidays, as well as making bots relevant to official server events.

I'm not the best at this next one oml😅 but interacting with the people who like your work also helps alot too in building a comfortable environment with them! Many people are afraid to comment or reach out as they might get blocked or something. So being active back will definitely help! I understand what you mean by motivation, it is a good thing to feel supported. If you'll like some more detailed help and have Reddit or Discord feel free to dm me! I didn't get any notification for this question so sorry it took so Long to answer!
