Gratitude.
I can lift my mood just by looking at a color and realizing how wonderful it is to see colors. These are the the things I am most grateful for, the senses that allow me to see, hear and feel the miracles of life around me.

Compare the surface of the earth with the surfaces of the moon or Mars! All of this amazing life growing, singing, moving. Millions of cicadas singing right now, leaving their burrows to aerate and irrigate the soil.

Glad that I have a little bit of knowledge to appreciate life's forms.
And it's mostly a free show!

I'll quote myself from another Mayo Connect discussion. (Grateful for these discussions, for all the folks sharing things that really matter!):

I found this video about 10 years ago.
It changed my life.
I remember some part of it every day.
