The Problem with Startup Advice
What you should be doing is thinking about this more like a Pinterest board—meant to inspire and not necessarily for you to just buy everything. When someone tells you they achieved success because they launched a mobile app, that means you should go off and consider whether it’s appropriate for what you’re doing to be on mobile. Does it work for your customer? Is what mobile did for someone else relevant to what you’re doing?
You still need to think with your own brain. Fortunately :)
