Demotivation and Nihilism

I am curious as to how Buddhism deals with demotivation, in the sense of lacking goals and aspirations, and with nihilism, in the sense of feeling things are dissatisfactory and devoid of reasons to crave them. I am aware the second aspect of my question is intimately tied with Buddhism, but I am somewhat asking: for someone lacking craving, what is there to be done in life? From the Mahayana point of view, I feel compassion is a noble aim, but I have trouble developping compassion. From the Theravada point of view, spiritual development is a goal, but without much obvious suffering to propel our spirituality we can get caught in cycles of lethargy, complacency. How does Buddhism deal with lack of motivation about *mundane, every day* things? What should one do in the worldly sense, when one isn't practicing? Thank you.
