Today I can complain because the weather is rainy or I can be thankful that the grass is getting watered for free.
Today I can feel sad that I don’t have more money or I can be glad that my finances encourage me to plan my purchases wisely and guide me from waste.
Today I can grumble about my health or I can rejoice that I am alive.
Today I can lament over all that my parents didn’t give me when I was growing up or I can feel grateful that they allowed me to be born.
Today I can cry because roses have thorns or I can celebrate the thorns that have roses.
Today I can mourn my lack of friends or I can excitedly embark upon a quest to discover new relationships.
Today I can whine because I have to go to work or I can shout for joy because I have a job to do.
Today I can complain because I have to go to school or eagerly open my mind and fill it with rich new bits of knowledge.
Today I can murmur dejectedly because I have to do housework or I can feel honored because the Lord has provided shelter for my mind, body, and soul.
Today stretches ahead of me, waiting to be shaped. And here I am, the sculptor who gets to do the shaping. What today will be is up to me.
I get to choose what kind of day I will have!

This fits hand in hand with a quote a heard (although I have no idea who originally said it), “What if tomorrow, the only things in your life were the things you thanked God for today?” This post is a great reminder to cultivate a heart of gratitude and thankfulness.
