oh absolutely! I’ve felt like that a lot before, and I couldn’t really escape it until I found my own “voice” I guess - until I got to the point where I was profoundly sure that I was going in my own direction, one only I could do for me, etc.
it’s really hard to escape that feeling if you constantly compare yourself to others, which is something I have to stress over and over to a lot of people, but at the same time it’s hard not to get inspiration if you don’t look at other art…
mostly it happens in cycles and you’re gonna feel like that, but you have to take solace in the fact that it’s gonna pass etc.
re-motivation comes from getting excited about either work or a personal project, thinking of ways you can get your own creativity into it, and so forth - I suffered from just believing pmd-e was basically garbage about a month ago, and had to take a short break during my vacation to just not think about it. then I started thinking about new ideas that excited me and… I cannot even express how much my heart wants to burst at all these ideas I can’t wait to get out. I’m so, so excited and inspired I can’t even contain it. so i just needed to take a break, talk to people who were still really into it, and go from there - that’s what helped me the most, and it might help you to make a small personal thing (with someone! it’s always fun to do things with someone who also gets motivated about art/the subject/etc), and to think about that in your spare time. having something that riles you and whoever’s working with you up… that’s truly the best thing, and it will just create motivation on its own, really!
