I haven't been sleeping well lately which is leading to feeling drained and lacking inspiration. However, I recently read 2 blog entries on the top 10 things you can do to live a more sustainable lifestyle that I think merit a repost:
6-10 top actions you can do to change your lifestyle to make it more sustainable.
The final 5-1 list.
Some of the items listed seem simple enough and worth consideration, not only because they're sustainable, but also because they would lead to improved quality of life.
