Hello, I'm Jo Fidgeon.
Welcome to Outlook, the home of personal stories on the BBC World Service.
They say the most successful people are those who aren't afraid to fail.
Skateboarder Justin Bishop positively loves it.
Yeah, I do love it.
Because when you fail for an hour or like even days when you're trying to learn a trick, when you finally get it, that dopamine that just hits the brain, that success that you feel is just unmeasurable because of, you know, how long it finally took.
And when you land something, first try, you do it fast, you don't get that feeling of success.
Yeah, but failing in your case might mean falling over a lot, hurting yourself a lot.
That's not quite so nice, huh?
It actually kind of is.
I always feel like whenever I get hurt, it just makes me feel alive, you know, Pain makes you feel alive.
Justin is a competitive skateboarder and wins medals.
But that wasn't the kind of success I was talking about.
I was thinking more about when life knocks you off your feet and you have to get back on again.
When Justin was 8 years old, he was told that because of a rare condition called retinitis pigmentosa, he would one day go blind.
The condition is a genetic condition, so it's been in my family for three generations before me.
So it was something that every child kind of had to get checked for, and it skipped a couple generations.
And at the time, the family thought, like, oh, it's probably out of the family now.
We might be good.
But when I got diagnosed at the age of eight, they could tell that it was in my eyes.
