Royalties are not how most writers or musicians make their living. Musicians by and large make a living with a relationship with an audience that is economically harnessed through performance and ticket sales.
No horse gets anywhere until he is harnessed. No stream or gas drives anything until it is confined. No Niagara is ever turned into light and power until it is tunneled. No life ever grows great until it is focused dedicated disciplined.
Better understanding of the natural world not only enhances all of us as human beings but can also be harnessed for the better good leading to improved health and quality of life.
