What we have is never enough. In this way, humans are all the same. The struggle towards the perfect life is never ending and universal. Physical beauty is a striking example of this global drive for improvement. Although standards of beauty are dynamic and varied, the push to meet those standards is universally shared. These standards are powerful because they draw on the shared phenomenon of competition and the desire for human companionship. These motivations for improving beauty are never going away, because we are never satisfied with ourselves.
