Shakespeare.
Early genius, like early cabbage, does not head well.
H. W. Shaw.
Maturity is most rapid in the low latitudes, where pineapples and women most do thrive.
N. P. Willis.
It seldom happens that a premature shoot of genius ever arrives at maturity.
Quintilian.
Nothing is less promising than precocity. A young thistle is more like a future tree than is a young oak.
