I signed up a few days ago. I never used GoodReads much. Last activity I had there was in 2013 and I kinda fell out of the habit of reading. But I picked up a book this week (and finished it in two days, haha), Recursion.
It let me import my GoodReads data and I've been slowly adding books to read to it. I think for me, the mental hurdle I had was the paralysis of choice. I decided to just pick a sci-fi book that was available for instant borrow on Libby and go from there. I currently started The Big Door Prize because I loved the first season of its TV adaptation. Happy to be reading again.
