Write, sing, direct, teach, pursue the things God has put in your heart. He's had a plan for us for a long time--even before we knew about it. When I look back on my childhood, some of the things I did, or other people expected of me, helped me to accomplish what I do now. I'm sure that's true in your life also.
When my brothers and I were young, our parents made us stand in front of them--and guests--and perform. We sang solos, told funny stories, played instruments, etc. TV wasn't as important then. Internet didn't exist. We were the entertainment. Today, I work with young people to help them stand boldly in front of an audience--to know beyond any doubt they can do it. I know that started in me when I was eight or so and singing "These Boots are Made for Walking" in front of my parents and aunts and uncles. Haha. Isn't it cool that God was working in our lives, nudging us, even when we were little kids?
