Hello hello!
Basically I'm just seconding everything Eckhart said haha; Wants and Limits are good, and a Character Catalog might help you keep things organized, if you wanna use one :)
Happy to meet you, hope you have fun here! Don't be afraid to reach out if you have any questions ^.^
P.S. If you feel like sharing, what is your first language? (I was a Lit/Linguistics major in college so I'm kinda curious haha)
