One of my favorite quotes:

"There’s a lot of boredom, there’s a lot of grind, and a lot of anxiety where you think  ‘am i as good as i think i am, am i ever going to really make it?’ But don’t worry about that. You know if you’re doing what you love, even if you’re not making any money out of it you are still better off than 99% of the people in this world who are not doing what they love. "
