Great post @josediccus.
You see, people fail to understand what it takes to survive or stand out when it comes to marketing or money making.
Definitely, from the illustration you gave of the guy that sells water, there are other people around that site that sells same water brand but fails to apply the necessary means of standing out.
Strategies - change of plans - consistency - hardwork
I could basically appreciate this factor as the key to a surviving business.
That was the point, hundreds of people sells water on a daily, but he chose to do his stuffs rather differently. It paid off because he won't give or relent. In so many places in the world, hustling spirit is what takes people far, beyond what they can reckon.
