For short stories I also just find them out. However, for longer works I need to really plan out how I want them to change, otherwise they turn out a bit flat.
Finding a character works well in the environment where they just need to exude a vibe of who they are, but when there is real discovery and change there needs to be identifiable markers in their story and that takes a lot more effort than vibing them out.
@crochet_mom314 You could try narcissism, its not for everyone though. You can never make a mistake if you are the only perfect being! Only problem is that everyone else ends up being wrong so much.
Curiously I started posting some videos on @rumblevideo to broaden out from just @YouTube and low and behold my first video on Rumble has garnered more raw views in 2 days than it has even gotten on youtube for the months its been there. Curious indeed...
