Climb every mountain
Climbing actual mountains might be how Duncan Chessell made his name but the Australian geologist and adventurer says anyone can scale the peak of any goal they choose.
It's five years since the 42-year-old South Australian achieved one of the world's most arduous feats, scaling the tallest peaks on each of the world's seven continents by reaching the top of Mount Vinson in Antarctica.
In the process he and his team also achieved a first, hiking from sea level to the summit of Mt Vinson across glaciers and mountain ranges that have never been traversed by another human. The trip, on foot and dragging their provision sleds behind them, took three and a half blister-filled weeks.
He has also conquered the world's tallest mountain, Mt Everest, three times in four attempts.
"If you've got a dream, don't just think about it and procrastinate, just put a timeline on it and make a deadline and get out there and do it," he says.
"No one is going to turn around and say 'here it is on a platter', you've got to work hard and got to go after it."
