The challenges change depending on the song. There are some songs where the lyrics are really a challenge and then there are other songs where the lyrics are there and the music is a challenge. And then you've got rock songs where the challenge is the tightness of the arrangement with the band. The music and the lyrics are there, but it's a challenge to get the arrangement correct. So I wouldn't be able to point to one thing. What the challenge is changes all of the time.

I like films, I like movies, I like playing different characters and working with different actors, and filming in different places. I like movies, because it's kind of a combination of every art, it's like it's picture, it's story, it's music, it's kind of like a clash and a collide of every art. It's really neat.

Often times, if a character is pretty straightforward, he or she is not as interesting to portray.

Gratitude is the root of joy.

Some of songs are autobiographical and some of it is more telling a story from someone else's perspective. It's healthy for me to do that because, oftentimes, it can become too narcissistic if I'm trying to express myself all of the time. My problems are what I'm going through and sometimes it's nice to take a step back and feel what someone else is going through and that can help.

That's what rock music is, I think - constantly searching for authenticity, and being as honest as possible.

Being joyful is a choice.
