The only true antidote to always wanting more, as this 8th Century  reminds us, is to be aware of, and rooted in,  our inherent completeness, an awareness which will contradict the arising feeling of never being satisfied.

There is a solitary brightness without fixed shape or form.
It knows how to listen to the teachings,
it knows how to understand the teachings,
it knows how to teach.
That solitary brightness is you.

Linji Yìxuán, Chinese Zen Buddhist monk, died 866
