From The myth of the overnight success by Chris Dixon:

Angry Birds was Rovio’s 52nd game. They spent eight years and almost went bankrupt before finally creating their massive hit. [..]

You tend to hear about startups when they are successful but not when they are struggling. This creates a systematically distorted perception that companies succeed overnight. Almost always, when you learn the backstory, you find that behind every “overnight success” is a story of entrepreneurs toiling away for years, with very few people except themselves and perhaps a few friends, users, and investors supporting them.

Truth is, entrepreneurship is not very romantic. But it is rewarding in every sense.
