wake up in the morning with a smile

I am a person who complained much in the past. When I look it back  I find my situation was not that bad and I could have lived it better. So I decided to live the rest of my life positively. When I jog and feel tired and want to give up, I think of the song " you are such a sexy cool girl. When I am worried about my work, I think of my baby niece waking up with a smile in the morning. I was so touched by her smile and it convinces me there are beautiful simple things that light our life.
