He has dived in the world's longest underwater cave and eaten a meal on top of an erupting volcano, but TV star Phil Keoghan still has a list of things that terrify him.
The Christchurch-born Amazing Race reality television show host was in Wellington today to inspire college students with his adventure stories and life philosophy.
Keoghan's "No Opportunity Wasted" (NOW) philosophy aims to inspire and motivate people to make the most of their lives by constantly challenging themselves.
He encourages people to write a list of all the things they want to do before they die.
"There's no such thing as write a list and check it off, then you're done," he said.
"In fact my list is extensive and constantly changing. I'm constantly adapting it and modifying it.
"I hope that even up to my last breath that there's still plenty of things I'm inspired about wanting to do."
Keoghan said he was terrified by the latest challenge he set himself, proving he was not completely fearless.
"I was on a celebrity game show the other day and it scared the hell out of me," he said.
"I was under pressure when everybody knows what the answer is and you're standing there with the clock ticking.
"It was one of the most horrifying, scary things I've done. But I did it."
Another challenge checked off his list was producing the NOW television show.
In 2006 Keoghan gave New Zealand contestants the chance to face their fears, but he said producing and hosting this show was a challenge for him.
"We took three of New Zealand's biggest scaredy cats and basically scared the hell (out) of them and took them from the couch to the record books in 72 hours."
The challenge ended with the contestants and Keoghan jumping off a suspension bridge, together, breaking an unofficial world record.
Keoghan hoped his speech to the Wellington students would motivate them to realise their "amazing potential energy".
However, he said their successes were dependent on the influences they had in their lives, and he hoped he would be one to them.
Children today had more opportunities than he did when he was at St Andrew's College in Christchurch, Keoghan said.
He said his NOW philosophy should be in school curriculums because "kids' minds are more pliable".
He said that unlocking the potential of children was most important to him.
"There can't be anything better than that. That's what you want for your kids and anyone you care about."
