Mornings are of different kinds. Dark or bright, cold or warm, cloudy or sunny. But they are always fresh. Who doesn't like mornings? It's starting a new day with renewed strength, it's a new beginning.
When you go to bed, you might be frustrated about the day that has just ended, and you didn't accomplish all your plans; and maybe it isn't a singular case. But you put all your hopes in the next day, making a promise to yourself that you will try harder and you will not let yourself be defeated.
