I'm Taufik from Pakistan. I've been working on Magento since last 4 years in a company.
Magento 2 was released at that time. Magento 2 seems tough at that time but by the time I get used to it. I was using stack overflow from start but now I want to become part of Magento forum as well to share my knowledge and issues I may have.
Welcome to the community forums.
The best way to start is to ask and try to help other into the forums.
You'll find information on StackExchange too and you can start diving into the http://devdocs.magento.com/ not only for learning but to correct and improve the docs.
We can't forget the powerful User Guide: https://docs.magento.com/m2/ce/user_guide/getting-started.html.
Another recomendation could be to be aware of Magento issues on Github: https://github.com/magento/magento2/issues (if you are technical, of course).
Also, you should read this post: https://community.magento.com/t5/Welcome-to-the-Magento-Community/Start-here-and-hello-from-me/m-p/5... (in particular the guidelines) and if you are not sure about how to use the forum you can read the FAQ: https://community.magento.com/t5/help/faqpage.
If you need information related with GDPR, you should check this: https://community.magento.com/t5/help/faqpage/title/gdpr
Finally, you'll need to get your hands dirty with the platform.
