1. Life lived entirely on feasting (food)
2. Life lived entirely on drinking (alcoholism)
3. Life lived entirely on merrymaking (parties, sex, carousing, etc.)
4. Life lived entirely on apparels (clothes, jewelry, fashion, make-ups, etc.)

It's simple to change to a meaningful life: Add God first and foremost; manage the four above in moderation; and be thankful for each day you are alive.
