One of the most important things we carry with us (if we're lucky) and one of the first things I fear we lose is the ability to view the universe and the people in it with a child's sense of wonder.
Decades ago, I made the conscious decision to hold onto this quality, and it takes conscious effort to put it into practice, because it forces me to step out of my concerns for tomorrow and regrets of the past and linger in the moment.
It's in the little nature things: the veins in a leaf, the sparkle of sun on snow, the texture of water, the glide of a cloud. And in the silly things: the burn of mint toothpaste, the galaxy swirl of foam in my espresso, the way my cats' eyes "blow out" when they stalk a string, sledding with kids.
And it's primary expressions are gasps, sighs, laughter of delight, and the question "Why?"
Hold onto it. If it's slumbering or dormant, reawaken it. Because life is as dull as cardboard without it.
