Concerning ourselves with the successes of others does nothing more than to distract us from focusing on our own. Perhaps this is one of the reasons why people never know what they have until it is gone.
Human beings absorb far more information than they consciously acknowledge. This results in the subconscious influence of information on our lives. It is only in moments where we take the time to reflect on our observations that we begin to become mindful of the things that we see but are never cognizant of. These are the little things that can be easily dismissed only to have a profound effect on our perceptions of reality.
