Everybody has knowledge about something. Having basic knowledge can help you figure out things in your day to day life that you may not know about. Knowledge isn’t always what you learned from books or in a classroom, you can attain knowledge from experiences. Knowledge is power only if you know how to use it. If you don’t know how to use it, it’s not going to help you.
The phrase “knowledge is power” means that knowledge is more powerful than physical strength and no great work can be done without knowledge. Knowledge comes with the power of influence and the power of making a point.
