Because of economic downturn in the world, most people have become jack of all trades and master of non. learning skills and not getting a mastery of them because they are testing waters on which of them will eventually pay the bills. I have a friend who during her spare time learnt soap making, baking, sewing yet she's not making money off these skills.
This is the same as most people who fail to build and grow their businesses, and this is common in business because not everyone can succeed.
But those who don't give up will evaluate the underlying problems and find solutions to activities that aren't profitable for them in business.
The fundamental mistake lies in their inability or lack of understanding how to run a business, because something we don't master is much more difficult to develop.
Many people are trapped by the stigma of building first and learning later. This is a mindset that makes it difficult to develop, especially when talking about entrepreneurship, because starting a business is not as easy as it sounds.
