Precocity is not a sign of genius, but genius is perhaps always accompanied by precocity. Andrew Lang
For precocity some great price is always demanded sooner or later in life. Margaret Fuller
What might be taken for a precocious genius is the genius of childhood. When the child grows up, it disappears without a trace. It may happen that this boy will become a real painter some day, or even a great painter. But then he will have to begin everything again, from zero. Pablo Picasso
