Mine isn't exactly anxiety but I struggle with choosing books and so I end up with horrendous ones a lot of the time

One strategy is that I read 2-3 books at a time. In case one is boring you have a second one to not drain your reading desire. (this help if you dislike DNFing as well)

My newly developed strategy is that I write down a number of titles I'd like to read this year. The number is my reading challenge of the year. This help reduce my 1000+ wishlist to a manageable number (this year it's 40 for example)

The thing with the list, is that I don't stick to it like gospel. I update it once a month or so based on new recommendations, so it doesn't become a job. Most of it stays the same, but aroung 5 change and so your list becomes more targeted towards favorites, but it also gives that sense of accomplishment as you see the list shrinking as you go through it. (unlike my wish list wich keeps growing infinitely.)

I hope this helps somehow.
