Just like any hobby or leisure activity, my interest peaks and wanes. Marie Kondo said it best, "if it's not sparking joy, yeet it out the window".
Pretty sure that's exactly how she said it.
Personally, I tend to enjoy listening to audiobooks over reading. I keep a looooooong list of books that look interesting so I can pick a title when I feel like reading. Note, I don't call it a "to-read" list because I am not going to read them all. I will never read everything on the list unless I stop adding to it at least ten years before I die. And that approach to a to-read list does not spark joy. From the get to, recognize this is not a list to ever be "completed" by design.
Make an account, subscribe intentionally, set your default view to "Subscribed" instead of "All" or "Instance". Then your original account is still there if and when you're ready to go back. Or just do this on your main account if you prefer.
There's no algorithm pushing content on Lemmy, it's how you choose to set your view and what you choose to subscribe to.
