It's the boredom that kills you. You read until you're tired of that. You do crossword puzzles until you're tired of that. This is torture. This is mental torture.
For the longest time I was brought up listening to only two genres of music, pop and rock. So in the past few years I've been trying to expand my interests because I think that you can only write to the extent of your knowledge, and if your knowledge is limited you can't write past that.
