As an entrepreneur, you need to ship the MVP to the end users ASAP. Jumping directly to building the product is generally a bad approach. That's where prototypes and wireframes come into the picture. Get the prototype ready and get users to start using it and iterate accordingly. Remember, for startups, speed is everything. PRO TIP: Start building an audience who'll use this prototype. Start a blog, facebook, Instagram pages, create an email list. This will save you precious time.
