Hi yossef,

In the future, avoid posting videos like this without some sort of explanation or introduction. Otherwise, it seems like you're promoting this content as your own, which I don't believe to be the case here.

Also, in the future, avoid posting this in #introduceyourself because it clearly doesn't belong there. If you have questions, you should check out the Steemit Etiquette Guide. It will help make your future posts great!
