I don't think we'll come up with a meaning to life or anything, (there probably isn't one anyway)... I look upon fate and destiny as determinable by choice, by the choices we make, and the choices those around us make. There is such a thing as destiny as technically, every possiblity could be mapped out. (not by man, we are nowhere near intelligent enough) So inevitably you are stuck with one of those possibilities, AKA destiny. But it is the choice that leads you into said destiny...
Hmm. I've re-read this original post a few times and I find that it is rather 'opaque'.
Using the title 'Meaning of Life' may have drawn a lot of people into the thread for a lively discussion (although, I feel it got rather sidetracked on the subject of Qualia), but I suggest that it may have been more apposite to have titled it 'Life is what we make it' - i.e. we have freewill and the choices that are open to us to pursue in life are the sole means by which we author our destiny.
Actually, the traditional notion of "Fate' is in conflict with the notion of unfettered choice and may call into question the tenability of the assumption of freewill given such examples as Alcmene (who was the mother of Hercules, fathered through deception by the god Zeus), the same could be said about Mary, mother of Jesus, but I decided to choose a less incendiary example.
I will skip over issues I have with your assumptions that only humans are capable of choice (surely Clyde the orangutan in the Clint Eastwood film 'Every which way but loose' was capable of making choices?) and that your assertion:
"There is such a thing as destiny as technically, every possiblity could be mapped out. (not by man, we are nowhere near intelligent enough)"
is somewhat undermined as I feel that you are overlooking the influence of both Chaos Theory and Werner Heisenberg's Uncertainty Principle. Instead I will directly address what I think is your main point, because time only flows in one direction (Feynman diagrams notwithstanding) we conceive of our lives as being a sequence of "irrevocable acts" - choices are made that cannot be undone. Not all choices are open to us at all times and the choices we make change that "possibility space" (removing some choices that our previous action has made impossible and making other choices available - not necessarily 'good' ones) and your personal philosophy that this succession of choices determines your state of affairs in the future ("AKA destiny") as if this outcome exists even though the outcome resides in a future that doesn't yet exist...
Hmm. When you say:
"But it is the choice that leads you into said destiny"
I have a real problem with this, as I don't think anyone can know what choices will be opened up to them, or made inaccessible, as a result of a prior choice. We can guess and generally be correct over short periods of time, in uncomplicated contexts with few dynamic variables in familiar and well understood scenarios (like: "Making a cup of tea"), but even inter-personal romantic relations are so hard to predict that there are bestselling books on the topic (like: "Men are from Mars, Women are from Venus" by John Gray). Repeated, pragmatic pursuit of a yearned for destiny is no guarantee that the identified goal will be reached during your lifetime, or that the desired state of affairs will still matter to you - i.e. you may achieve your goal of becoming a millionaire, but be too old and infirm to enjoy it.
Ruminating on this further, I think people look at other people's life-histories (reading celebrity biographies, etc.) as they have this notion of following (or avoiding) a similar destiny themselves. They look for patterns: "Where did X get their lucky break?" "Did they recognize it as such at the time?" "How did they overcome their problem with Y?" - which they feel they could apply to their own lives. The problem with all this is that you only get the biographies of those whose life-histories consisted of an interesting sequence of choices that the biographer was able to find a connecting theme for which dramatized the person's life with some notion of inevitable destiny. You must realize that the media select, emphasize and dramatize reality as story, as consumers of media like to be told stories not a billion flat facts.
Because media is a part of culture and culture changes the way we think about reality, others and ourselves, it is forgivable that you made the mistake of saying that the choices we make in life lead into our (single) destiny. We simply cannot talk about destiny before we have lived a life as the choices we make take us into many alternative possibility spaces and create usually humdrum, unthematic, undramatic, lives with multiple future personal and inter-personal state of affairs.
So. To summarize, I don't think you can talk about your own personal destiny as you are obviously here in the present talking about an unknowable future and destiny is really something other people infer from your life-history after you are dead (or have won a Gold Medal at the Olympics, say) - i.e. after the events important to the formation of your life-history have all taken place and have been deemed to be successful, usually by someone else.
As to the 'Meaning of Life', I have already addressed this point in another thread "The thread for random statements", so if anyone really wants to know, ask and I'll repost it here.
