"Rejoice, O young man, in your youth, and let your heart cheer you in the days of your youth. Walk in the ways of your heart and the sight of your eyes. But know that for all these things God will bring you into judgment." (Ecclesiastes 11:9 ESV)
It is beautiful to be young, life is full of wonder and possibility. Make the most of life and its possibilities, but remember that you are setting the foundation for your future.
