Before we start this piece, let's get clear about one vital point: that anyone (except the truly impaired) can learn anything if they use the right procedure for learning and have a reasonably good curriculum.
There is no legitimate excuse.
The single most important thing that adds to one's life is learning: an adding of workable knowledge that permits one to better manage one's life and to harvest all of what one wants, and, of course, knowing what it is that one truly wants.
Is there a limit to what we want to learn?
Is there a limit to how well you want your life to be?
I suggest that we just keep on adding workable knowledge - and adding in a systematic way with proper expertise, so that we learn most effectively.
And, of course, we would, as we are journeying through life, be harvesting our lives, living in balance - and we would not just be learning for just learning's sake, like some intellectually fun thing (which is ok if fulfilling, but is not the goal).
We would be learning for life's sake, either enjoying a particular area of learning (as a recreational thing) or learning something that enhances our lives in some way (even job skills will add value plus confidence for a better life).
But those who do not even develop the base, who have not learned the vital basics will be adding on to an unstable structure.
The sister site on educating about life is TheLifeUniversity.com, which will be reformatted to some extent and developed more, but which has some valuable insights and oversights.
To the Khan Academy:
In looking at Bill and Melinda Gates Foundation's statements of scope, I was struck by the lack of teaching the skills of life. The subjects, with some exceptions, were around technical skills (which of course are needed in order to learn "good thinking"). But an accomplished technical person who doesn't know how to manage his life and health and beliefs, etc., will not be as powerfully effective and beneficial to the world or to his own happiness as one who knows how to create effectiveness and unconditional happiness.
I write about this in www.thelifemanagementalliance.com, but I lack the resources (time) to achieve the excellence in educational effectiveness that you have.
What I would like to see, possibly considered by the Gateses, a program implemented to teach that effectiveness - of which the ultimate effect, from there being a greater quantity of more powerful healthy thinking people will be a rippling outward of more of these people being created and on and on, to where there are more people effectively applying their brains and skills to making the world a better place.
There is so much possibility around this.
What do you think????
