For those that it doesn't help assure a successful life journey, are there other viable ways that do help? And, if so, what are they, and how do they work?
Of course, I am not an expert but I have a sense there are those who are not quite so goal oriented.
I know those who are more concerned with the present moment, who are not concerned with the future or accomplishment or measurements.
I think of spiritual masters, gurus, monks, etc, who seem to have released desire, or those for whom life is not about obtaining happiness, believing happiness is the natural state of the human.
Also, there are those who have obtained Moksha (not our Mok... smile), and who feel there is no need to be here or anywhere, nothing to do, nothing not to do.
While a goal oriented life is common and works for some, my observation is that there are other ways of experiencing peace, joy, happiness, etc.
