= LUCK - is a coincidental, random outside occurence;
= HAPPINESS - is an individual state of mind.
Emphasis is on individual. It definitely comes from inside. Whether it is lasting or passing, whatever it triggers it - is as individual as we are ourselves.
Therefore I do not believe it to be possible to find a "recepy" or "guideline" on "how to be happy".
Yes, listening to yourself, finding out your wishes beyond satisfaction of basic neeeds is a way in the "pursuit of happiness". Note that the wise people devising the phrase said "pursuit", not "achieving". They were very aware of the fact that it is not a stable state of mind, but an eternally on-going process, in which values and goals are re-defined permanently, as we change.
In times of crisis it is of the utmost importance not to lose your head (Marie Antoinette)
