What does fiction offer that non-fiction does not, and vice versa? Should people in certain professions read more of one than the other? Should people in the arts/creative space read more fiction? Do business/marketing people read enough fiction? Can we learn as much from fiction as we do from non-fiction? Should we just do what we prefer? For example, if you prefer fiction and I prefer non-fiction, should we just stick with what we like? Or should we push ourselves to try other genres?
