What I tell all new bloggers:
-Assume they've heard it before, why should they read your version of it?
-Be careful about sourcing your images, make sure you either have a stock subscription or explicit permission before using an image that's not your own.
-Just. keep. posting. The times where my blog has had the most traffic were when I posted consistently, even if not all of the content was epic.
-Have fun! Find your own voice and before you know it you'll have your own following. It's a very crowded and competitive space, so best of luck!
