While browsing today, I came across http://dailygood.org/ which tells us that;
"people who practice a daily gratitude intervention (self-guided exercises) had higher levels of alertness, enthusiasm, determination, attentiveness and energy, compared to the group who focused on hassles or thinking of how they were better off than others. Gratitude is good for you. Really good for you".
I always give thanks at the end of my Yoga practice, but I guess a daily journal entry, listing all we have to be grateful for would be a good thing. My sister summarised all she has to be grateful for in her life, at the start of the new year in her blog http://morleysathome.blogspot.com/ and I plan to begin by giving thanks for something every time I post. See my list on your right. Just watch me become more alert, enthusiastic, determined, attentive and energised. You should try it!
