Human beings are always striving to improve themselves. It is not just a social imperative, but comes from a inner sense of always feeling there is something else we should be doing with our lives, or doing what we do better. Or as that old adage says, we think that ‘the grass, is always greener on the other side’. Adding to the sense of discontent with what they have. People rarely appreciate this, until they no longer have it. Sadly, for many this realisation often comes too late.
We live in a society, where success is measured in terms of material success or social standing. We cannot entirely blame peer pressure for this, for the way in which we are made, means that ego is something that often leads people around by the nose. I believe it is primarily a inner motivated force. Though we will often try to blame others when things go wrong, as they often do.
