These are very good things to know.
If you dont mind a little constructive critism. The post could just use a little more than just bullet points. Perhaps explain how and why a person should have these pillars in place and how to use modify them to use in any situation. If there would've been a little more to it than just bullet points I would've given a 100% upvote.
Again, I'm not trying to be a jerk, but just wanted to let you know how it could be better.
