Just one word. Earthling.
To be read and interpreted as a gentle reminder to live in the present. To be thankful and mindful for this opportunity of Life and all of the concepts it is built upon.
As often as you can, remember to acknowledge the oxygen coming in and out of your lungs. Feel your feet on the ground and the clothes on your back. Be thankful for the eyes you have to see and the brain that allows you to feel. What a blessing this life as an Earthling is.
