Whatsapp's founder got turned down from Facebook and then he got rehired again when Facebook bought his company for $18b.

If he had been hired that day, maybe there'd have been no Whatsapp. A single situation can be good or bad depending on how you look at it.

I'm pretty sure he added at least $1b to the price of whatsapp for the compensation of emotional stress he got back then :)
