Some days I wake up feeling buoyant, bouncy and ready to enjoy the best in life. Other days, well, I feel a bit like a slug - sad, or blue, or worn. Was it something I ate the night before? Is it part of my cycle? I've been thinking that if I can just identify the pattern, I can maximize the good days and avoid whatever causes the bad.

Knock Knock’s Daily Mood Tracker is a fun, simple tool to quickly make note of how you’re feeling every day. It would serve well as a gag-gift for your friend who’s an emotional roller coaster, by why not use it as a way to track your own causes and effects? You’ll start to notice that coffee and donuts in the morning make you grumpy, but after yoga class you’re flying high.

There’s nothing like more awareness to help you make better choices in your life. And after all, isn’t that what sustainable living is all about?
