After encountering number of references to it, I now read myself the
Steve Jobs Stanford speech. Interesting example of how "who is saying" is sometimes not less important than "what is said" or maybe even more important.
Of coarse, one should also keep in mind that people are different (that is important point that often is forgotten when general advices are given to broad audience) and that many recipes that work for one man would not nesesseryly work for another. For example, " follow your heart and intuition" advice my work good for intuitive type of people, but not for those who's intuition is less good.
I recall how two chess champions disagreed on a similar subject. Capablanca used to say something like "Sir, if you see good move - don't hesitate, do it.", while Lasker is quoted saying "if you are sure you see good move - think again, maybe you miss something."
