Answer :
I'm not the best at it, but I can teach you at least the basics...
It's like writing a book almost, the actions are suppose to mimic the character's personality, so when you're trying to think of your muse's actions, keep their overall attitude in mind.
I did only a couple, but that's just the advice my friends taught me...and I hope it helps you in the future...but if they're any specific questions you want to ask, feel free to ask me ^^
