It doesn't matter how old you are, whether you are in your early teens and you are preparing for high school. Or wether you are in high school you are preparing for what college you want to get into. Or maybe your life as you knew it flipped upside down and start over.
Setting goals, listening and learning from others that have successfully done what they have wanted to do. Maybe just trying something new that you had no idea you enjoyed. Sometimes you just have to risk it for the biscuit.
