I love music, it kind of comes naturally and has always been a part of my world.
High school is about finding who you are, because that's more important than trying to be someone else.
Stop hoping, start believing.
Find things you're passionate about, and find others who are as passionate as you are and will focus on giving you an opportunity to shine and to have your moment where you can be in front of others to show what you can do.
Don't let the world around you defeat the belief within you.
I think the community that you're in really can define your ability to be at peace with your circumstances.
