No. I have vaguely kind of yearly TBRs, books I mean to read (or try) that year, but if I do not, it's fine. I got a release calendar and some books are insta-reads (but if it is not that is also fine).

I got a truly very large TBR and of books I mean to try, and that was a bit angst provoking (the DUTY of reading TBR books! It felt like slacking off if I did not) but honestly I got over it. I just can not read, or enjoy reading, books on schedule, so I try to be analytical about my exact mood (no depressing books if I am stressed...), alternating genres, if I "indulge" in just published new books (which somehow seem always more attractive) then I should give also a try to old TBRs (which somehow often are great).

I just try to pay attention to my mood, and changing genres, and themes, and lengths and all. I quit books at will and sometimes I sample paragraphs from 5, 10 books before I decide to start one. I am fine with this, it is what works for me.
