At a certain point we need to grow up; we need to look inside ourselves for our inner guidance. There are things most human beings know; they just don't want to know them. They know deep down that certain things in their lives are working or aren't working, that certain parts of their lives are functional and others are dysfunctional. But sometimes, as human beings, we don't want to know what's not convenient. So we pretend not to know.

Sometimes I just listen to classical pieces of music to take me away from my work. That's what I kind of do to wash away the notes that I've been working on all day. As human beings we need to sleep so that's kind of one of my little tricks.
