I have a strong preference for being alive.
In the midst of the sense of tragedy or loss, sometimes laughter is not only healing, it's a way of experiencing the person that you've lost again.
I find myself going to places where I really have no business, speaking to these people in a whole other field that I have no extensive knowledge of. But I do it very often because it scares me.
The thing is when you're... well-enough known, you get asked to speak places, and they don't really think about whether or not you're qualified. They just want somebody that will be a drawing card for the audience. So it's up to you to decide whether or not it's foolish to get up and speak to these people.
