Maybe it's human nature, or possibly it's due to lack of resolve and discipline in parenting - but whiny, entitled people abound. There are so many trivial things every day that really don't make a hill of beans of difference in life regardless of what happens. The Butterfly Effect was an interesting movie, but I really don't think our life's outcome is determined by every tiny event. What changes your destiny is how you react to each event.
I think my ability to live out of my car is because I live my life like I take my coffee - black with an indiscriminate amount of sugar thrown in and then I deal with it.
