1. Learn in public

If there's a golden rule, it's this one, so I put it first. All the other rules are more or less elaborations of this rule #1.

You already know that you will never be done learning. But most people "learn in private", and lurk. They consume content without creating any themselves. Again, that's fine, but we're here to talk about being in the top quintile. What you do here is to have a habit of creating learning exhaust. Write blogs and tutorials and cheatsheets. Speak at meetups and conferences. Ask and answer things on Stackoverflow or Reddit. (Avoid the walled gardens like Slack and Discourse, they're not public). Make Youtube videos

22 Hacking Sites, CTFs and Wargames To Practice Your Hacking Skills
InfoSec skills are in such high demand right now. As the world continues to turn everything into an app and connect even the most basic devices to the internet, the demand is only going to grow, so it’s no surprise everyone wants to learn hacking these days.


However, almost every day I come across a forum post where someone is asking where they should begin to learn hacking or how to practice hacking. I’ve compiled this list of some of the best hacking sites to hopefully be a valuable resource for those wondering how they can build and practice their hacking skill set. I hope you find this list helpful, and if you know of any other quality hacking sites, please let me know in the comments, so I can add them to the list.
