TRUE HAPPINESS, long-term, is only found in one place. It comes from within, not from without.
Unfortunately, our society is based on mass belief that it is from 'without'. And that getting EVERYTHING YOU WANT is Happiness.
God gives us what we 'need' (and sometimes it sucks)
Lucifer offers us what we 'want'. (to put it in simple religious terms).
Which is what this 'story' is all about.
