Often we think that we know a concept until we hit a hard rock and realize that all we thought we knew was just the basics. If you are open minded, then you will create a room for learning which will help expand your knowledge base and be called megamind who becomes a hero from his evil deeds.
That is just ideal and an opinion to some people while others believe in constant knowledge as the best way to keep up.

Does pilling up knowledge help you understand a concept or the deeper you go the more you get lost in search for knowledge. Well who thought knowledge can be an addiction!

If you can’t explain it to a six year old, then you don't understand it yourself - Albert Einstein

Sometimes you feel saturated with knowledge and you feel like adding more is a burden and impossible but again, how do you know that you know what you know?

Teaching others is one of the many ways you can assess what you know. While explaining a concept to others, you often get unexpected questions that will help you think clearly on the concept. A teacher is no different from a presenter as they all lay down the concept for others to learn.

Often we present what we have learnt and mostly it is a hard gamble between words and the concept. Sometimes the audience is listening and other times, it is not and as a presenter, you have to master the audience and keep them alive and this in return, builds your confidence.

There are concepts considered rocket science to an ordinary man but were derived from our ways of life and the people who come up with those concepts are considered geniuses because they invested their time in understanding the concept and be able to explain it to a layman.

You may ask what I now know and I would respond with a series of knowledge I acquired including but not limited to valuing my time, leading the conversation in the presentation, understanding the concept and explaining it to others your way but still be open to understanding other people’s view.
