I don't think biological goals are the only purpose to life, or even the highest purpose. We're all here to worship God through our efforts, and work out our salvation "with fear and trembling".

I see marriage as the most-common vocation, but there are other vocations. I'm saying the opposite: if marriage is your vocation, that you are called to, then take it seriously and focus on it. Don't put it on the backburner or on your To-Do list.
