I want to learn Magento 2 . Any good sources?

I am learning Magento 2 from these Magneto 2 Tutorials
I want to find more sources and videos from where i can easily understand the tactics and implement it properly. I got little bit confused reading articles so is there any video tutorials to learn Magento 2 ?

Well, first the docs. And the magento codebase itself.
