When I'm singing a song on stage, I hate hypocrites. If you don't put yourself in that lyric and emote and be what that lyric says that you are, then you're just going through the motions and you're being hypocritical. I just take that same approach with acting. I just take the dialogue and I emote it and become that. I use the same technic.
It is through sorrow and suffering, toil and tribulation, that we gain the education that we come here to acquire and which will make us more like our Father and Mother in heaven.
