Old Indian saying. This is my rough translation with words added for clarity.
Someone gives a monkey a piece of Ginger. The monkey tosses the Ginger.
Someone gives a top chef a piece of Ginger. Chef enhances his preparation with ground ginger.
Moral of the story: If a numskull dismisses your talent, then move on and find someone that actually understands/appreciates your talent. Of course, this assumes that your "talent" is real.
