if u seen the movie 'Limitless' it sould resonate with the psyche of how i believe our society is conditioned into a delusionally bipolar'grass is greener' mindet where we are either very happy/successful, otherwise we are down in a ditch waiting for the next opportunity to get back up there and be ecstatically happy and successful in the future.what about incremental. to me, that's how savings and investment actually materialize. heck, the very word itself 'invest' should encompass the fundamental of not consuming today in order to have more tomorow. i myself have times when i am broke but thats almost always right after a close where i invested than liquidated. my final thoughts are practically nobody on BP is living in the horrid shantytowns of any continent for matter where they are living in starving conditions with no food/water available on a daily basis nor having nothing to call their own other than the clothes on their back. such is the case out there for some large portion of some 8 BILLION humans on this planet. many, many if not most people out there all over the world don't own anything at all except the clothes they are wearing right now. likewise, many/most people on this planet don't have a practically endless supply of food so they dont go hungry. here in northamerica, luckly even homeless folks if there hungry can simply find out where the nearest 'soup kitchen' is and get a wholesome meal on a daily basis indefinitely. we have so many resources at our fingertips that it is so easy to start saving up 100s of dollars a month even based on minimum wage (whereas a family overseas living in rural areas with no local jobs other than living off the land, as is the majority of situations across the globe, may be lucky to even make $100 a YEAR!).
