If you mostly read classics, try reading a modern novel published in the last 20 years or so. Or, if you mostly read modern novels, try a classic, preferably one published more than 100 years ago. Was it as good or bad as you expected? Was it perhaps worse? Or better? After this, will you be reading more classics/modern novels, or will you stick to reading what you have always read? In the last couple of years I have been reading mostly books published in the 20th and 21st centuries, but I have promised myself that I will read more classics this year.
