In the first issue of O, The Oprah Magazine, Oprah wrote:
'We are all the causes of our own effects . . . That's why I'll
never stop asking the question, "What do you know for
sure?"' In the fourteen years since Oprah wrote those words,
she has retired The Oprah Winfrey Show (the highest-rated
programme of its kind in history), launched her own television
network, become America's only black billionaire, lost beloved
pets and adopted new ones, watched friends and colleagues
come and go, celebrated milestone birthdays - and through it
all, she's continued to offer profound and inspiring words of
wisdom in her monthly O column, 'What I Know For Sure'.
Now these thoughtful gems have been revised, updated and
collected in What I Know For Sure, a beautiful book packed
with insight and revelation from Oprah Winfrey. Organized by
theme, these essays offer a rare and powerful glimpse into
the mind of one of the world's most extraordinary women.
Candid, moving, exhilarating, uplifting and dynamic, the
words Oprah shares in What I Know For Sure shimmer with
the sort of wisdom and truth that readers will turn to again
and again.
