Finding Time

So I am totally new to this whole blog thing...mainly because I don't have time to write a blog let alone update the thing. I tried myspace, facebook, and now this? Who am I kidding! I didn't have time to keep the other 2 updated so I thought I would try a 3rd? But the 3rd time is a charm right? The thing is, is that I see all these people that have blogs and they update it at LEAST once a week and most are SAHM? WHERE DO YOU FIND TIME!!!??? I only work 10-20 hrs a week, but with a little one, tying to keep up a house, being a mom, wife, and working I feel like I have no time to myself and when I actually do, I want to sit and do NOTHING!? So all you SAHM's please share your secret with me!
