It is disheartening for any creator to put so much of their time and themselves into something and see it fade into the sea of posts. You're proud of something you made, it's only natural to want people to see it! It can be hard to stay motivated in the face of nothingness. It's why you suddenly notice someone not putting out videos as much or making art as often. Silence truly is deafening when there's a lack of acknowledgement for your efforts.
When people say the best way to support them is to like and share things, this isn't a sunshine and rainbows BS statement. It is absolutely and positively the truth. Support through paid subscriptions, Patreon, Ko-Fi, etc are all fantastic and definitely help facilitate their work, but never underestimate the value of a new set of eyes seeing what they do. If someone does something you enjoy, let them know! Hit that thumbs up! Tweet it! Drop it in your group chats! Linking to someone's page is great, but linking to something specific you enjoyed is even better. Leave comments about your favorite parts. Doing something that says "hey, I saw your thing and I liked it" does wonders for any type of creator's confidence and self-esteem.
Don't think it's worth posting to your own social media because you think you have a small following? Don't be silly! Those pesky algorithms are affected by views and sharing, and literally anything and everything helps. You keep seeing things on Twitter from people you don't follow because other people liked it, right? This is how that happens! No one is inconsequential or too small to be important to helping creators feel valued and that their work has meaning.
Creators, this goes for you too! I know it can feel like a competition sometimes, but everyone wins when you support each other. A view you send to another artist isn't a view taken from you, it's strengthening the web of creator support. What goes around, comes around!
Short version? Show things you like to other people and they'll probably keep making it.
