Don’t bite off more than you can chew. If everyone lived by this montra, the world would change for the better. It applies to so many aspects of our ailing society–
foreign policy: don’t go in without an exit plan
birthing rates: don’t have more children than you can support- both financially and emotionally
economy: don’t spend money you don’t have
obesity: literally, don’t bite off more than you can chew.
This would change society at large to a more self aware being that does not over-consume, over-spend, or over-extend. Obvioiusly this does not speak directly to the developing nations that struggle to survive on a daily basis. But I do believe that if people were generally less concerned with digging themselves out of various overwhelming situations, we’d be all together more inclined to help those in need.
