I sure liked your definition @humanearl, but in my own opinion, I think that the ultimate definition of success is one's own satisfaction with what we have achieved. I am not talking of that never-ending drive that the successful have, to do more and ever more, but rather when that individual looks at what he has done so far and feels satisfied that it was "enough"!
"Enough" is enough to support their dependents, enough to share one's excess in philanthropy, enough to empower others by giving them employment perhaps, and to pay taxes to support the country. Thank you
Do we ever become truly satisfied by the things we achieve? do we really know when enough is enough?
I mean look at western culture. Buy Buy Buy. Spend more so that you will feel better. I find it hard to believe that we all at some point become truly satisfied with achieving things. We may move on to other things once we've accomplished something in one area but still we want more of something. This is just our fallen nature.
For our achievements to be really worthwhile I think they should not be tied to the things of this world. (money, titles, rank, possessions, etc). Only then do I think we feel more satisfied in our life.
