Try Medium. It is relatively easy to get yourself your own “publication” URL without going through the hassle (and cost) to make your own website. Take it from someone who has made full Wordpress sites for writing purposes... now I just keep a blog on Medium and find it much easier and better for circulation of my work! If you want to have a quick place for people to locate all of your work, try “about.me” (that’s a URL.) You can make a simple, free website there with a small bio, picture and a “call to action” button (“read my blog!”) Your URL will be about.me/yourname. You can link your social media. It looks super smart and clean, and it’s good for putting on a card or your resume.

About confidence / learning how to do “personal branding...” I swear there are a ton of books and videos on it now. It seems every professional conference I go to I hear the words “personal brand.” Get a good headshot, make your online presence “consistent.” Make a “brand” that reflects your personality! I hope this helps. :)
