It's not for you to know how it's all going to turn out or how it's all supposed to be. It's not for you to know and it's not for you to control.
Your job is to just be you. Be passionate, alive, inspired, creative, emotional, determined you. Your job is to figure out what you care about, who you want to be, what makes your spirit come alive and to go and do just that.
That's all you need to do. That's all you need to know. I'll take care of the rest.
