I have been away on a very relaxing, no computer, no phones, no electricity type of camping holiday (ok, they turned the generator on for a couple of hours every night so we could have a hot shower) and came back to this great link from Mel. Have a read. I found it to be very motivating and really put things into perspective. It doesn't matter how far you fall behind in anything, really, an extra 20 minutes spent each day can catch it up before you know it. http://www.beckyhiggins.com/blog/2010/04have-you-fallen-little-behind.html
And I loved the bit about it all really being about reminding us what a great life we have and feeling gratitude for our family and friends, our homes, our lives, everything we experience. It's not about stressing that we are behind, it's about enjoying the little things every day.
