Reading many books at once VS not reading enough


Usually I like to read many books at once (2 to 4), but lately  I cant really concentrate on them all. I get distracted by one or two books and when I go back to the others, left unfinished, I just lose track and decide to reread them from the start. Sometimes I don't even pick them up.
This also happens  when I finish a book and I just don't know which book to read next, and I start several books to see which catches my attention the most, wishing I four eyes instead of two.

Maybe the problem is that I  didn't find the right books that match my mood atm since I there are several unfinished books in front of me that I can't pick up.
