Buy no more than 4 new books a month. All other books must be borrowed either from friends or library, swapped or received as gifts! That way some of my reading will be recommended by someone other than Amazon. I get so lazy with the 'If you liked this, you might like this' thing that I've found the variety of what I read has reduced significantly.
I went to the library last week and they actually have a great range and it's free! What an awesome hobby.
Other than that I would like to read some non-fiction this year (last year the only non-fiction I read was about OJ Simpson and even then I'm not sure how factual it was).
