“There are two kinds of fears: rational and irrational- or, in simpler terms, fears that make sense and fears that don't. For instance, the Baudelaire orphans have a fear of Count Olaf, which makes perfect sense, because he is an evil man who wants to destroy them. But if they were afraid of lemon meringue pie, this would be an irrational fear, because lemon meringue pie is delicious and would never hurt a soul. Being afraid of a monster under the bed is perfectly rational, because there may in fact be a monster under your bed at any time, ready to eat you all up, but a fear of realtors is an irrational fear. Realtors, as I'm sure you know, are people who assist in the buying and selling of houses. Besides occasionally wearing an ugly yellow coat, the worst a realtor can do to you is show you a house that you find ugly, so it is completely irrational to be terrified of them. -Lemony Snicket”

Variant: We fear things because we value them. We fear losing people because we love them. We fear dying because we value being alive. Don’t wish you didn’t fear anything. All that would mean is that you didn’t feel anything.

2000s, To Live Beyond Our Fear (2007)
Context: Barack and I talked long and hard about this decision. You know, this wasn’t an easy decision for us, because we’ve got two beautiful little girls, and we have a wonderful life, and everything was going fine. And there was nothing that would have been more disruptive than a decision to run for President of the United States.
And as more people talk to us about it, I mean the question came up again and again. What people were most concerned about: they were afraid. It was fear. Fear, again, raising its ugly head, in one of the most important decisions we would make. Fear; fear of everything. Fear that we might lose. Fear that he might get hurt. Fear that this would be ugly. Fear that it would hurt our family. Fear.
But you know, the reason why I said yes was because I was tired of being afraid. I am tired of living in a country where every decision that we’ve made over the last ten years wasn’t for something, but it was because people told us we had to fear something. We had to fear people who looked different from us. Fear people who believed in things that were different from us. Fear of one another right here in our own backyards.
I am so tired of fear. And I don’t want my girls to live in a country, in a world, based on fear.
