When the Homily is about Immunology

Trailblazing

A business related email I get often comes accompanied with the following inspirational quote:

Do not follow where the path may lead. Go instead where there is no path and leave a trail.

Initially I thought it quaint, but then I thought for a while: Unless you believe that you and perhaps a small number of other enlightened few are the only ones worthy of such advice, what would be the point of leaving a trail?
