Do something good

You have the power to change someone's day.

Turning 15 reminds me of the songs "Not a girl [not yet a woman]"
Sometimes we can feel powerless but in reality we are more powerful than we realize.

YOU have the power to make someone happy.  It is so simple that we take it for granted. 
It is as easy as greeting someone or giving a compliment.

Try to make a difference each day not only in the lives of others but yours as well. Remind yourself of all the blessings in your life. You are an amazing person. You can make others happy.
