In need of focus

Maybe it's the pregnancy, but I feel like my head is swimming all the time with thoughts, ideas, things to do, what to blog, what to make for dinner, what to do with the kids that day....and it just gets overwhelming! I think what I need is a good planner. I need some way to empty my head onto paper and get things organized. I'm usually jotting down my to do lists on 3x5 cards. It works but I need something more. I need something that tracks the long term too. I wish I could afford a nice franklin covey. It's back to school time though; I bet I could find something decent at a good price right now. I'm going to have to start looking. I bet some yoga would clear my head...it's been a while and I could use the exercise and the focus that it always seems to bring.
