Choosing a Highly Profitable Niche and Dominating It in 2021

When it comes to starting an online business, the first thing you should consider is what you already know. Make a list of your interests, hobbies, education, and employment history. At this time, don't make any changes to your list. Include anything you can think of that you do or enjoy.
Take advantage of this opportunity to think outside the box. Remember any classes in college, high school, or continuing education where you learned something that could be useful to others? Keep track of the books and publications you've read (and the information you have gleaned from them). This is the opportunity to put any knowledge you have rattling around in your head down on paper as a strong point.
