Tomorrow and plans for tomorrow can have no significance at all unless you are in full contact with the reality of the present, since it is in the present and only in the present that you live. There is no other reality than present reality, so that, even if one were to live for endless ages, to live for the future would be to miss the point everlastingly.
Those people who develop the ability to continuously acquire new and better forms of knowledge that they can apply to their work and to their lives will be the movers and shakers in our society for the indefinite future.
