Chris Dixon dispels The myth of the overnight success:
Angry Birds was Rovio’s 52nd game. They spent eight years and almost went bankrupt before finally creating their massive hit. Pinterest is one of the fastest growing websites in history, but struggled for a long time. Pinterest’s CEO recently said that they had “catastrophically small numbers” in their first year after launch, and that if he had listened to popular startup advice he probably would have quit.
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.
