The vicious cycle of life - people who have everything, take
things for granted, people who don't, desire for it. People who are
sheltered, were whacked hard by reality when their shield
disappear, while those who have been through hardship, learn
appreciation and value. 
Cosmic cycle of life - everyone has their learning issue. What
comes around, goes around. Just take care about yourself, your
family, friends and those you care about: the underdogs,
unfortunate, etc - the rest of the world, don't bother. 
Cheers
