Might be a bit easier if you posed specific questions or talked a bit about what exactly it is that you would like to know the “meaning” of. Not trying to be harsh, but your post, while appreciated as yet another potential member of the community, is a bit broad and there are MANY existing posts, subjects, responses here that could give you an overview of some of the stuff you want to know.
I for example, don’t know WHEN to stop writing. Could write you a BOOK, and I’ve been accused of doing so in fact, but then in trying to address all the possibilities based on your “just starting” with no idea, implying a high degree of confusion.
There are a LOT of people here who will immediately chime in as soon as you post something specific they feel qualified (or not 😉 to respond to.
