If you haven't already listened to it, you might like "What Is The Light", from "The Soft Bulletin" by The Flaming Lips. It's a bit on-the-nose but is basically a poetic encapsulation of what you just wrote; Wayne Coyne wrote many of the songs on that album while metabolizing the death of his father, and pulls it off without ever becoming funereal or morose.
I can't quite put my finger on why but have always felt that album --- basically one of the three best pop/rock albums of the last 20 years --- was uncannily resonant for (our yes yes lazily romanticized concept of) entrepreneurs.
