My stomach did a slow roll. I knew we'd come to the place in the story I feared the most. I began to breathe very fast. (Kidd 251)
Lyrics | Taylor Swift lyrics - Back to December lyrics
You should always be able to be happy when you look back on the past. Even if it is sad there is always a silver lining. There should be nothing you want to change about the past because you are happy with the present.
Do Not Dwell On The Past Or Future, Instead Live Each Day Like It Is Your Last And Never Regret What Is Said Or Unsaid
