Strait up, I know the meaning(s) of life ENTIRELY!
“The best life” actually has to do more with width and growth. If you lived longer then humans do, you would have more time to learn more, do more, develop and aquire more – this would be a better life because of advancement.
One of the main meanings of life on earth is to evolve and change; get more adapted and capable. It’s too damned bad that we can learn so much in a life time, but our DNA doesn’t learn didly-squat! It’s hardware vs software issues mang, lamezillia.
But if we are talking about Hedonistic “best” – find a really hot peace of ass, practice your favorite sports with your buddies, take on a tolerant and liberal attitude as you make lots of friends and love freely, etc.
OOOORRRR: [Buddha style]
The silancing of desire is the silancing of suffering. You’ll get some nirvahna if you eventually let go of all want [but will still have your willpower and your satisfying of your own needs].
And then there is me… A sort of pan aproach. I believe that everything is good. I want atheists and theists to exist. I want all sorts of different races, opinions and values to exist.
Theoretically – I’d written about “the cure for all evil in all realities through out all dimensions and time” – [long story short] Dan discovers that “evil” is a motion striking against a life form, and it is a vector motion that can be re-directed towards a more pure self-advancement/growth ideal.
Principals of math and shapes/dimensions can be applied to all subjective cycles and systems, in effect, mapping the essense of consciousness – and once we have the map, we really know where we are going!

Soft hugs from Dan, byebye.
