Do the Thing You're Most Afraid Of
I think somebody said this once, but I can't remember who it was. Fear can be an outlet for making a serendipitous discovery about God's untapped potential in you. The very thing that most terrifies you may turn out to be something you're actually good at doing; or it may be an essential stepping stone in our development as human beings.
One thing that scares me is the death of my parents (hopefully a reality I won't have to deal with for some time still). My parents have been a formative and supportive influence, and selfishly, I'm terrified about having to go through the experience of seeing them age and die. But doing the thing I'm most afraid of will make me a stronger, deeper person with a stronger, deeper relationship with God—and the same can be true for you. When you do it, you'll discover that the thing itself really wasn't as scary as you had made it out to be; and you'll feel proud that you did the thing that made you afraid. And, you'll be able to say that you really lived.
