First time blogging

Ok so I read my friend Lisa's blog today (loved it by the way), and decided that maybe I should start a blog myself. My mom keeps telling me I should and post all the good grocery deals I find etc. Then I thought to myself "No one wants to read my ramblings". Then I thought to myself "people in middle and high school use to read my stories and ramblings all the time. Maybe I should blog". So here I am! Not sure where to start, but figured I should post something...right???
