Someone once said, " If you don't have a passion worthy dying for, you have nothing worth living for. 
If you are not willing to suffer for something, you really aren't passionate about anything."
The question is, what are you passionate about? What's that something that causes you to look forward to the day ahead the moment you wake up in the morning? What's that something that causes your blood to pump hard and gets you adrenaline rushes the moment you think about it? What's that something that causes you to react like Popeye the Sailor when he says, “That's all I can stands, and I can't stands no more!” and you must make a stand for that something?
So, what are YOU passionate about?
Even when you have something you are passionate about, the real question is,
Is what you are passionate about worth living and suffering for?
