I get stuck because of physical health reasons. My three things I try to kickstart it again are:

1. dark mode on my tablet, can make a huge difference for me
2. reading free page turner crap I get from the online ebook store (in dark mode of course)
3. reading novels I already know the general plot of

The built in reader on my tablet keeps track of time read. It's set at five minutes, so I try to at least get to that target with the free page turner crap.

Reading fluff for five minutes is easier than taking on something substantial. And if it doesn't happen on that day, that's ok, I can always try again later.

This is what works for me. There will be something which works for you, so try and keep trying until you find it. If something doesn't work for you, that's ok. You'll find one that does.

(Have you tried short stories? Easier to complete than a novel.)
