From David Warren's Before the beginning:
The advice of a solid old Anglican priest — back when the Anglicans had a use for solids — was to retain one’s balance. “Don’t try to do everything at once,” he said, after my conversion on that bridge over Thames. In particular, “Don’t try to believe everything at once. It is bigger than you, you shan’t be able to do it.” And, “Never abandon your skepticism. If it doesn’t make sense to you, leave it and get back to it later.” And, “The trick to walking, whether you are a babe or very drunk, is: one step at a time. Those who get ahead of themselves tend to fall over.”
