Yesterday is history
Tomorrow has yet to come
And today is a gift
Don’t be ungrateful
Do not be displeased
You have been granted the gift
The gift of sweet life
Make the most of every minute
You never know when there will be no more
Do not waste time
Guessing the future
Or living in the past
Live in this moment
Right here
Right now
