The thing that makes the biggest difference in everyone's life is passion. Passion is the drive for everything you do. Without the passion to make music you wouldn't play an instrument or sing a song. Some people have more passion for something more than others and that's what makes us all truly unique. You may think the thing you have passion for is silly or nerdy but it's not because it's important to you. Your interests will change over time but you will always have passion. It's something that never goes away and it's part of being human.
