I'll pat myself on the back
and admit I have talent.
Beyond that, I just happened to be
in the right place at the right time.

Ethel Merman (1908-1984) 

Talent alone won't make you a success.
Neither will being in the right place
at the right time, unless you are ready.
The most important question is:
"Are your ready?"

Johnny Carson (1925-2005)

Le talent ne suffit pas,
il faut lui annexer le temps et l'argent.

Michel Conte (1932-2008)

Le talent a besoin de gestion.

Andre Siegfried (1875-1959)
