It is not often a blog starts with a quote from Soren Kierkegaard, but bear with me on this one. The Danish philosopher wrote:
 
So only one lack remains [in our time], even though not yet felt…the lack of difficulty. Out of love of humankind, out of despair over my awkward predicament of having achieved nothing and of being unable to make anything easier than it had already been made, out of genuine interest in those who make everything easy, I comprehended that it was my task: to make difficulties everywhere.
