Do you remember that post that you received in the Welcome e-mail from dev.to once you've registered?

{% link https://dev.to/acoh3n/how-to-make-the-most-out-of-devto-ag0 %}

A part of it has deeply echoed in me.

> **_Share your experiences with us_**

> *How many times you thought to yourself: "maybe I should write an article about that" and then didn't? I'm going to guess that it happened more than a few times. The short answer: just do it already!*

> *Even if it improves the life of just one person, isn't it worth it?*

> *And by the way, it doesn't matter what you write about or if there's a million articles on the subject already. Your experience is unique. Your perspective is unique. Your background is unique. So just please share it with us.*

It is indeed very valuable to share your knowledge, particularly for you if you are learning something new.

As you can see in the following image

![Learning Pyramid](http://blog.envole.net/doc/l/e/learning-pyramid.jpg)

If you are just listening, as you did numerous time at school, you are just going to have a retention rate of 20%. That is not a lot. :-(
But if you teach others, then you are going to have a 90% retention rate. That is way higher. :-)

It is basically because if you want to teach something you must understand it properly from the beginning to the end.
In order to explain why it was designed, made, etc like this, you must understand much more about a technology than when you are just using it. And you don't really know why it is working but it gets the job done and that's all that matters.

So, especially if you are not an expert, it is **extremely** valuable to teach something or just talk about a topic that you are learning. Because you are going to have a **90% retention rate**.
So that also means that if you are making a presentation about something and that your audience is not interacting with you, it is useful only to **you**.
That's why I always start my presentation with a statement about questions and interactions that are more than welcome because otherwise this presentation is going to be useful only to me.

If you are at College or in a company, you should try to make presentation about something new you learn as frequently as possible.
Don't be shy, everyone knows something that someonelse doesn't know and is eager to learn, and...
> *If it improves the life of just one person, isn't it worth it?*

Moreover, I am sure that it is going to be useful for a lot more than just one person.

Feel free to use that "Knowledge Pyramid" image in your presentation to make people aware of it and free them from asking questions and interacting with you.

Your next step, is to decide what to share and start writing.

> *Happy writing*
