London: Actress Naomi Watts does not believe that success is "everything" and finds life in Hollywood "uncertain".

"Acting is such an uncertain kind of life. You struggle so much at the beginning of your career - at least I did - and then you suddenly find yourself working all the time and after six or seven years you realise that maybe work and success isn't everything," a website quoted the 43-year-old as saying.

Naomi was recently seen in Clint Eastwood's "J. Edgar" opposite Leonardo DiCaprio.
