Love is measured in time. The time we are willing to spend with people we love, or doing the things we love. That's why we get so frustrated when our time is not well invested, or even feel hurt when the people we love are not willing to spend the same amount of time with us...
I think is inherent in humans to be driven by a cause. However, we must be able to differentiate between sensationalism and true facts. Otherwise we risk to sacrifice many things in life for the wrong cause; which may even include our own happiness.
