In the creative sense. What helps you to think? Books, movies, songs, etc. This just came to mind and I decided to make a topic. For me it depends on what I want to come up with, depending on which I could name a few songs for each mindset I want to have. Sometimes there might be a book or videogame that inspires me too although I prefer music for when I want inspiration.
I'm pretty visual, so if I see a piece of artwork that resonates with me, I tend to get inspired to create my own artwork. I'm at a learning phase, so learning techniques by imitating things (but still adding my own spin) is generally how I roll.
But outside of art: as long as I'm giving myself space to think about things organically, I can get inspiration.
