There is nothing else that you really need to look for or do, if you really learn to observe yourself and life. Everything that you will ever need, can be found in this plethora of information. Self-observation will reveal to you that all this is much more than you can comprehend or take in, at once.
I do not care to find the reason why we are not taught this at a very early stage, looking for answers in the past and blaming others or myself. That would be a big waste of energy for nothing, leading me nowhere. My time of interest is the present, which forms the future. That which I care about is who I am right now and what I am doing.
