What's the process one can go through to come up with a winning idea? What considerations should the entrepreneur pay heed to (like resources, market) to figure out if it's something that's possible with a high chance of succeeding?
As a Business owner myself, I would offer that the first step in this process should be some self reflection. Reflect on what your passions are, what makes you happy, what do you enjoy doing? You are going to step into an arena where for a considerable period it's going to be all on you or the select few who decide to partner and start this journey with you. I say that for a couple of reasons. Number one, is the fact that this will not be an easy process. There are too many challenges along the way for to not be a) passionate about your work b) enjoying the work you're doing. I would argue you that at 80 percent of entrepreneurs start in search of fulfillment that the mundane world can't offer.
Next after I've found what my passion is, I need to discover what's my niche in the industry. Where is my wheelhouse so I can get in and start on my small piece of industry. Here is now where obviously resources like finances, a space to work from, and customer/client base have to be then defined.
After that I would then begin a process to define and identify myself on digital and social media platforms. Everyone tends to take the easy way and Facebook, I personally use linkedin, twitter, and a blog on my own website. I also use platforms as such.
