While painting last week, my daughter (who loves to color, paint, and draw) said, "Daddy, one day, I'm going to be an artist."
I corrected her: "You already are an artist."
All of us aspire to be someone or do something. Let us not forget that beginning such a journey actually makes us that thing or person.
Declare who you want to become and begin living in such a way. And then watch as you get to where you'd like to go well before you know it.
