Musing Monday Prompt Dec 8

How long do you wait after finishing a book before you pick/start another one? How many books do you have planned ahead or do you pick up random books from your tbr pile (if you have one)? Do you review right away or keep reading and come back to it later?

I have a very systematic way of choosing novels, almost OCD to be perfectly honest. I bought a book entitled 'The Good Reading Guide' and I follow it religiously. I do have particular genres that I like, but I follow the creed that in order for my writing to excel, I must read as many different books as I can. Its extremely rewarding to read in this fashion since I always end up finding books that I wouldn't normally bother touching and being quite surprised at how much I enjoyed it. Its not all good though, some books are better than others. Captain Corelli's Mandolin was at times beautiful, funny, moving and tedious. I am trying to navigate myself through the 'The Big Read' top 100, but my local library is not that extensive. I have since discovered classics online though, which has saved me a lot of trouble.
I tend to pick up books straight after finishing the previous one, but it takes a while to read them and I have this ridiculous need to find out about new concepts and vocabulary as soon as I discover them, which requires me to have ready access to a dictionary and encylopedia. I hate not knowing about what I am reading, and not finding out would rob me of one of reading's greatest attributes. They are explorations from the comfort of my armchair. I have a massive list of books that I want to read, and I find it extremely distressing that the list will probably exceed my lifespan. As for reviewing, that's something I have yet to take up, but I intend to in earnest. So much to read and so little time.
