Jim Harbaugh shared his famous enthusiasm with a pair of newlyweds in an interesting way

Jim Harbaugh being Jim Harbaugh

Jim Harbaugh is a personality unlike anything that has been displayed at the highest level of college football. The head coach of the Michigan Wolverines is famous for his eclectic behavior and unbridled passion for his craft and, earlier this week, Harbaugh shared some of that trademark enthusiasm with a pair of newlyweds.

Yes, you read that correctly.

Just in case Harbaugh's handwriting was (slightly) illegible, we transcribed it for you here:

Seth & Kristen,

Congratulations on behalf of the 2016 University of Michigan football team on your May 28 wedding.

If I might offer a suggestion:

"Attack every day with an enthusiasm unknown to mankind."

Every Day — Together.

Much Happiness,

Jim Harbaugh

Yes, that is the head coach of a college football power sending a handwritten note to a couple that he does not know with marital advice. Furthermore, it is Jim Harbaugh passing on "an enthusiasm unknown to mankind" and it is even written with a very thick blue marker for reasons unknown.

Things like this do not need full explanation, simply because Harbaugh is capable of just about anything. Still, Seth and Kristen will certainly never forget this investment from the face of Michigan's football program and this is just fitting for Harbaugh's public persona.
