What will really happen if you aren't able to read every blog on your list today. Will they stop being your friend? If they are your friend, then no, because they know that like them you have times when even if you are thinking of them you might not be able to talk that day. You might be overwhelmed with other things.
What does worry and stress get us? It gets us more worry and stress, and I know that I personally don't need more worry or stress. So I let go. I forget about catching up. I live in this moment and breathe in its freshness, its newness. It feels like a warm breeze on a sunny spring day.
Maybe today is the day that you can start to forget about catching up. Just let some of those things go. Enjoy this moment. It is simple and serene living at its best.
