How to Start a Blog

So, I've always been fascinated by blogs. For example, does anyone really read them? And what makes my life sooo interesting that I feel the need to start one? And who will want to read it? But, I figured, what the heck? If people are posting what they ate for lunch on facebook, then I could start a blog. And some events in my life are definitely more interesting than the ham and cheese sandwich on THE BEST rye bread EVER <3 that you just ate and felt the need to share with 599 FB friends (478 of whom you don't really know that well). And then, when you got sick from said sandwich, all  599 of us had to know about that too - 'nuff said, I can start a blog.
