Marriage is a colossal gamble, or rather, a very great adventure

You and I are faced with one of those situations (which fortunately are not very numerous in one lifetime) which cannot possibly be adequately judged beforehand. It strikes me as a colossal gamble, or rather, a very great adventure. And personally I am considerably exhilarated by the risks! ... The greatness of the adventure perhaps consists partly in the fact that as a Catholic I can marry only once! But, as with being born, perhaps once is quite sufficient! In the Church, you know, there is a great heightening of every moment of experience, since every moment is played against a supernatural backdrop. Nothing can be humdrum in this scheme.

Marshall McLuhan in a letter to his future wife, 

The Medium and the Light

I love the idea of being exhilarated by the risks of the adventure of marriage. We tend to cringe away from risk. But, as Marshall McLuhan says, think of how big this moment is, with the supernatural background. We've got to look past staying safe and and hedging our bets in the big things of life. Think of adventure!
