What excites you, drives you.

If you have a goal, no matter how hard you work you will not complain. Why? Because you are focus on reaching that dream. You will do everything you can just to make sure that you reach that goal! 

You are happy doing the hard work as you know some day you will be getting that dream. 

I read this somewhere: "Great things never came from comfort zones". I truly believe this. You need to work hard for what you want and what you deserve. If you stay within your comfort zone, you will not grow. 

Cheers!
