Though with numerous ways to put it into words, entrepreneurship is generally defined as the act of being an individual who undertakes innovations, finance and business acumen in an effort to convert these into economic goods. I simply define it as every person's actions aimed towards turning a profit, most commonly the act of starting a business. There's no exact measure of time or profit for a business to be considered still as a startup other than if you consider the business as still new then it still probably is a startup.
The profit margin for all types of businesses will depend a lot on the person starting the business, the idea of the business, the product or service involved and many other things. Check this article for possible factors that may affect your profit, suite101.com/content/types-of-business-s... though, blogging turns the highest profits since there is no physical product or resource needed to invest on. Most of the time also, there is no manpower hiring required or involved in this system.
Hope that helps and good luck.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
