So much of our lives are made up of constituent parts. The people we spend our days with, the jobs we do, the places we live are all made of smaller things. Days are the same way.
Don't waste time looking for something that may never happen, that perfect day. Bask in the small good things that make up your day and cumulatively make it good. Days are not always "happy, happy; joy, joy" and expecting such will likely end in frustration. Recognizing the tiny good things that make up your day will make it better and make it easier to share. Sharing your reasons for a good day is a small self-fulfilling act that passes it forward.
What tiny good thing happened for you today? How did you share it?
