I always joke about letting the haters motivate you. Everybody has that in their life, people who doubt them or make them feel less than they are. It just takes faith and belief in yourself, and you've got to dig deep into that. That has to come from you - nobody's going to give you that.
When I was young, I was just about hard work. But as I got older, I did experience anxiety, doubt, judgment, and it's so easy to lose yourself for a second.
