It’s important for entrepreneurs to believe in what they are selling — in essence, to create a field of distortion around themselves that makes it seem like anything is possible with their solution. They just need to make sure they don’t believe what they’re saying to the point of distorting their own view.
I often find myself saying to entrepreneurs “your job is to mix it and serve it, just don’t drink it yourself!” This usually slips out of my mouth when I’m talking to an entrepreneur who is pushing their idea so hard that it seems like they are trying to convince themselves of its brilliance, though in most cases I think they actually believe it, which is what concerns me.
This doesn’t mean it’s bad to serve the Kool-Aid to others (metaphorically speaking, of course). Really, as an entrepreneur that’s a huge part of your job: selling others on your dream. And while it’s absolutely critical that you make a case for your product or service that has people fighting to buy it, you have to make sure you critically assess the reality of your situation.
