Indeed, the satisfaction of a job well done, is it's own reward.

All the cumulative wealth of the world can never deliver health or happiness (though it MIGHT make it easier to acquire). 

If you do not believe this statement, just look around at the walking dead (celebrities, moguls, politicians, etc.) that seem to acquire a great deal of it.

As the country song lyric goes: "There ain't a luggage rack on the hearse..."

All of the above seem true enough.  Another idea that I would like to bring to the table is simplification.  Have you noticed how people nowadays have gargages full of stuff.  Every cupboard in their house is stuffed to the brim.  They even own a storage unit.  I would just like to remind people that by simplifying your life the path to happiness is alot easier.  Maybe because it is not so cluttered.  We all know that materialism is rampant these days.  But, we really can exist much more peacefully  in a simple environment that is not cluttered with stuff.  Stay away from StuffMart as the VeggieTales character say :)  Make it a happy day, de-clutter your environment and ask yourself, do I really need all this stuff to be happy or does all this stuff make me confused?  You will experience a huge amount of freedom when you don't have to worry about all this stuff.  I say simplify, simplify, simplify!   You might as well get used to it, because there is only one thing we can take with us, our soul!    That is my 2 cents...anyways.
