how do people do it?

I have been following a few blogs for the past few weeks, and I cannot for the life of me, figure out how other Mom's have the time to blog everyday! Not only that, but they actually use correct grammar and spelling! I will be the first to admit that I am NO super mom. At the moment, my living room is in serious need of the vaccum cleaner, but it scares the baby, so that's my story and I'm sticking to it!
I have an old friend who I haven't seen in about 19 years coming to visit next weekend. I am already stressing about how much work I have to do before next Sunday! I've seen pictures of her house and it is immaculate! She has 3 kids who she home schools and her house is still spotless! I am getting agita just typing this! Lists, I'm good at lists, so I need to make one of all the things I have to get done next week.....I wonder if I have time to paint the entire inside of my house?
Hopefully I will be better at blogging in the future. Posting every 6 months isn't very interesting to read, I know, especially for the 1 person who follows my blog!
