Does anyone else plan seasonal reading challenges this way?

For every seasonal challenge I make a list for each achievement with the books i would read or that are already in my tbr shelf. Then I look for books that can count toward multiple achievements at once.
I somehow managed to find 5 books that covered the entire challenge. So instead of having to read a huge number of books, I only need those 5 to complete everything.

I honestly find it so satisfying to optimize my TBR like this.

Does anyone else do this, or am I taking Goodreads challenges way too seriously?
