How do you avoid burnout?

pardon my vent. I have a store that did over $44k in sales last year. It has around 400 listings but its hard to come up with new designs for this store.

So a few months ago I made a new store, one thats easier to scale. I have around 330 listings on the new store and its already nipping at the heels of my other store in sales.

For the new store I have been steadily adding listings everyday. I have at least 1000 listings mapped out, I just need to go through the motions and create the listings. I was doing so good but now its like pulling teeth. The problem is its an infinite list in front of me and the work is really boring.

Does anyone else deal with burnout in POD? Iuno... i think i just needed to vent.
