Center Sidebar header text?

Hello,

I searched for an answer but I couldn’t find one that worked for me. I want to simply make my sidebar text centered if possible. I’m not exactly sure how/where I should do this, I tried it in the CSS but that didn’t work out so well…

My website: http://anukindofview.com/

As you can see, the sidebar header text is currently to the left. I’ve been playing around with things on my site and I think centered text would look a bit better.

Any help will be appreciated. Thanks to all who help in advance.
