Life doesn't care how I feel, but _I_ do; and I want to live life in a way that makes me (and the people I care about) feel good. Empathy, imagination, and innovation are important for that - and fiction helps feed those.
I enjoy reading fiction, mostly for escapism although the good ones also enrich me, but there is plenty of non-fiction that can feed those qualities. Non-fiction that focuses on the psychology, motives and feelings of people, and focuses on special, different , or creative individuals, might dk just that.
The autobiography "Lab Girl" comes to mind.
