I figure it this way, I may or may not randomly succumb to a car accident, but if the next day I lost my hand I wouldn't give up on programming, I'd learn how to type faster with one hand. I bet the other one gets in the way anyways.

My point isn't that random isn't a big deal, or that people don't ever overestimate themselves, but that people shouldn't look at it like that anyways, it keeps you in control of your own life.
