What Project & Stories do you like the most and what should I focus on. (Patreon)

That I'm finally on break, I've been wondering what I could do to improve my Patreon.

I've been focusing on writing my stories and book chapters, but the drawback is how long they take me to complete. 

That being said there's only so many projects I can work on it once, but I also want to deliver on my Patreon rewards and commissions that I owe.

So I would like to ask, what posts and rewards do you enjoy the most? Should I focus on?
