Building a startup is a very difficult thing to do. In a recent blog post, Ben Evans (I highly recommend you follow his blogpost) mentioned - “If you take a normal, mature company to zero in a few years, you probably screwed up, but if a startup doesn’t make it, generally that’s just the risk you took. Pulling a company into reality out of thin air, through sheer force of will, isn’t easy. But you’re only reading this because of the entrepreneurs who took that bet. This is how invention works.”
