Good company in a journey makes the way seem shorter. — Izaak Walton
Sometime starting your journey is very difficult. You know your product or service, you likely have a good understanding of who will want what you have. But the hard part is knowing how, where and when to get your company started. Starting a small business is often lonely and with no one to 'sound your idea to' that are not your family or friend (who would likely agree regardless of their real opinion) it can be challenging.
Best place to start is by detailing your product or service on paper, not just having it in your head. Then look at what benefit that offers people and what might be missing from it.
When you have done this you are ready for your next step!
