I had a really bad temper growing up, something I worked on for years. And now I’m able to recognize different emotions and I’m not governed by them. Doesn’t mean I don’t have them. I’m human. But I’m not easily moved. … I think a lot of people look at things as being restrictions, but that kind of shows me the way they view life. I don’t view it as restriction ― I look at what I can eat, what’s going to be the best source of energy for me.

Like, "I think, I should've done this a long while ago." Like, "Why didn't I research this before?"
