Sean Swarner was diagnosed with two unrelated forms of cancer, once at age 13 and again at 16, and at one point doctors only gave him 14 days to live.

Swarner, however, not only defied the odds to survive, he has gone on to become an inspiration to others, climbing Mt. Kilimanjaro ten times and becoming the first cancer survivor to climb Mt. Everest.

On Fox and Friends this morning, Swarner - who is now cancer free and is the co-founder of the Cancer Climber Association - joined Steve Doocy and Brian Kilmeade and explained that he started down this road because his parents always pushed him to be the best that he could be, and that included staying active during his cancer treatments.

"They're doing a lot of studies now that show that if you are active during treatments, you can handle the treatments a lot better," he explained.

Swarner - who also spends his time doing motivational speaking - suggested that many people approach their goals backwards, starting at base camp and working up the mountain, to use a climbing analogy.

"So take that mountain analogy and flip it upside down. Start successful and in your head make sure it's real before you even begin. You'll never fail," he said.

Swarner explained that through visualization and self-belief, he feels he has already climbed a mountain before he's even begun, and it's a strategy that can work in any aspect of one's life.

He added that death and human mortality are very difficult things to deal with, but all his experiences in treatments and climbing have given him a unique perspective.

"We should not worry about dying. We should worry about not living a life that matters," Swarner concluded.
