Size 16

So I went from a size 20 to an 18 in pants, but yesterday I was wearing my 18s and they were falling off of me, the legs were big and baggy, and as I looked at my reflection in a store window I thought to myself...sheesh you look homely lady.  Then I went into Old Navy and tried on jeans and BOOM.....size 16.  I was totally psyched!  I haven't seen 16 in a few years now.  Next stop is going to be 14s!!!!  Baby steps...I don't want to make big goals and then get frustrated if I don't meet them when I feel like I need to.  I want to have realistic goals, so size in this case, does matter!!!
