I believe the idea of starting a business or let me say the main goal is to make money, generate profit and course see the business expand over time. It will be a waste of time, effort and resources if you start a business that fails to meet it's set targets as listed above.
And the only way that can happen is if the business owner does not understand what it takes to achieve success in a chosen line of business.
As simple as some businesses appear, there are some hidden trade secrets that need to be learnt, and how do you learn if you don't subject yourself to apprenticeship to understudy an expert in that field.
It's just like reading and writing, you cam only learn how to read and write only if you submit yourself to be taught by a teacher.
So, apprenticeship is key. It can come in whatever form. But it is important to go through that period of learning.
