Animals live in a moment-to-moment world of surviving. Right now.
We, on the other hand, mildly live in that world, but we also live in a future world. We can look forward and visualize what we’ll need to survive (and thrive) three days, three weeks and three years from now.
That raises the tricky question of trade-offs. Sometimes we must sacrifice something in the present in order to make a more certain future.
Relationships, – especially marriage – are an example of this. Male nature is to satisfy sexual hunger with less than perfect discrimination. To forgo that drive in the interest of creating something valuable is a choice to trust that higher goals are worthy of giving up short term pleasure.
That choice also pushes back the chaos, the chaos of unrestricted gratification. It also demonstrates faith in our ability to maintain those long-term advantages, but like any investment in the future it requires conscious maintenance. That’s the hard part.
