Want to Innovate? Become a "Now-ist"

I like the idea of a now-ist for getting to the innovation part, but I fear about how things go in the long run if we keep coming up with ways on getting things done in the short term. As from what I understand being a now-ist you dont have much focus on planning it for the long run you are just focused on delivering the goals and trusting on your network of resources. Yeah, that definitely sounds interesting but would it be good for a startup to keep following this approach as it scales up?
