First up and most importantly of all, the measure of success of the ignorant and the measure of success of the intelligent are worlds apart. So yeah, I have a bunch of Bananas or I have more Bananas than everyone else, might work for monkeys but it does not work for intelligent people, nor does striving to achieve marketed definitions of success when you can see through the marketing (ignorance is bliss right up until they shut the gas chamber door and start pumping in you final breath). Now having a very broad sense of humour about all of that crap and that tied into the certainty of the 'LACK' of immortality of the vehicle of you temporary entrapment, it's demands must be met, else you do suffer in many ways, will provide many opportunities for humour and happiness not that you will often bother to share that with others, they will often take offence at the reason for your humour.
There is deeper meaning to. Have as much fun as possible, whilst causing the least amount of harm possible. Added to Annoy those that break the first rule, apparently it's necessary but don't forget to have fun whilst doing it. And of course Care and share in the wonders and joy of life. Winning at life, is most definitely not winning at greed not matter what the psychopaths say (they can never be happy as they lack that emotional ability regardless of the lies they express about it).
Happiness in more intelligent people, a measure of their sense of humour as balanced against the level of destructive deceit the can see and understand in the society of which they are a part. If you believe the sewer you are wallowing in is paradise, you'll likely be happy, however if you see the sewer for what it is, unless to have a sufficiently wry sense of humour, you likely will be unhappy. There are of course a range of intoxicating agents to re-introduce you to the world of bliss in ignorance of your youth, even if only temporarily so and fuck all those ignorant annoying ass hats who would deny that escape from them and their offensive nasty attitudes and behaviours. Greed the only measure of success, well, fuck that, I mean how persistent do you really need to be, to be able to light up a joint ;D.
