A friend who started his PhD at the same time as me, and finished a while ago, answered a question on LinkedIn recently. Paraphrased, the question was, "Why would someone do a PhD?" and his answer was something like, "Well, you get a title, and you never know, it may come in handy some day."

Compelling reasons, for sure.

This "WTF am I doing" moment, was brought to you by the universe.
