Being thankful heals

I think I've read studies about how gratitude has a measurably positive effect on one's health--cardiovascular, nervous system, etc. It makes a lot of sense to me--approaching life with gratitude and a "glass half full" rather than half empty attitude definitely does a lot to ease anxiety, stress, and depression. I find that focusing on the positives and thanking my stars for all the little and huge blessings in my life can be the fastest route toward getting out of a funk. I remember reading a self-help book that advised noting three things to be thankful for each time one wakes up and before one goes to sleep. It's still an activity I partake of to this day!
