Dear Past Bloggy Self,
Wait, stop, don't publish that first review yet. Don't do ANYTHING blog-related yet. Just go take a look at other blogs, learn the ropes, get a feel for the community- there's so much you don't know and it'll be a lot easier if you don't have to figure it out as you go along.*
On the same note, don't pick that generic background that 200 other blogs have. Seriously, you can just look up html tips, or free blog templates, or really anything other than the templates Blogger offers.**
Get a Twitter, a Facebook page, and a Tumblr much sooner, especially Twitter. You'll get to talk to other bloggers and authors and publishers, which is just as awesome as it sounds.***
Ultimately, Past Bloggy Self, the most important thing you need to know is this: post what you want to post. Post about Harry Potter or feminism or John Green or whatever makes you happy. Don't feel pressure to measure up to other bloggers- real blogging success is when you're proud of the content you're publishing.****
Best of luck,
*Then again, figuring it out as I went along DID teach me a lot about blogging. I had to start with plot summaries before I could get to the actual plot critiques. And even in my not-so-spiffeh bloggy days, I was able to make some great bloggy friends.
**If I had just looked up free templates, though, then I wouldn't have learned basic html, or started playing around on Paint.net.
***But waiting a bit allowed me to "figure out" Twitter before I jumped in.
****There's really no clause for this one. Just wanted to say that maybe all the mistakes I made as my Past Bloggy Self were also learning experiences. Just a thought.
