You probably don't need to know that starting a successful enterprise - online or offline - can be very hard, but it does help to know why. This way you can focus more clearly on how to reduce that hardship.

You could probably go on all day about the people in your life and which needs they have, but let's focus on business.
Typically, an individual has one primary need he or she wants to be met - whether inclusion, control, or affection. A business, on the other hand, needs all three needs to be met in order to be healthy (i.e. profitable and influential).
If a business doesn't stand out, if it isn't well-positioned or well-differentiated, then customers won't choose it over other businesses. Thus, it has to get its need for inclusion met.
If a business doesn't have control over its operations (products and services, income, expenses, staff, etc.), then the business will fall apart. Thus, satisfying the need for control is a huge priority.
And if a business doesn't have loyal customers, customers that love the business and support it, then the business will have a very difficult time growing and thriving. Thus, the need for affection must be met.
This is, of course, no easy task, but knowing this gives entrepreneurs three important questions that they must ask themselves continually in order to build a successful business:
Anything beyond the scope of these questions is superfluous.
