Ideas vs Execution
The mythos of Silicon Valley tech innovation is very much about ideas: once you have the next great idea, success is assured and you'll change the world in no time. But it's just not true: execution is much more important. Julie Zhuo writes about it, pointing out that Google wasn't the first search engine - nor was the iPhone the first smartphone, and so on. Execution of the idea makes all the difference - and critically, that means that past failures of an idea don't necessarily invalidate the idea. Just make sure you have the right people to execute!
