The swimmer won gold in 2004 with Michael Phelps and just a few years later he was jobless and living in his car. Klete Keller... has experienced the highs of beating Olympic swimming legends like Ian Thorpe but, after his winning career was finished, he sunk into a deep depression.

Keller lost his marriage and his job over the course of 24 hours. His life fell apart and he spent 10 months living in his car.

The American used to blame everyone but himself for his situation but now he has come to terms with his past. He simply struggled with real life once swimming had ended.

He says he just got lower and lower.

Now, Keller is rebuilding his life and says the biggest lesson he learnt was that life takes a bit of discipline. This is his story.
