I quite agree with you on this:

Creating a successful business starts with seeing an unmet needs, and then going on to crave a specialty around it.

Before starting a business, it's important for one to have a business plan so as to have an in-depth knowledge of the business before venturing into it and not just that alone, to be successful as a business man or woman or an entrepreneur, you need to be providing values. Let your business solve people's problems and with this, one will surely thrive in this area.
