Each of these tend to describe the same trait of highly creative people the nature to be child-like: untainted by what they know, naive, exploratory, risk takers, etc.

Cross-training (renaissance "man" education or liberal arts training) is reported as one way to achieve this. Yet the U.S. has had that type of school program since the 1840's and it hasn't produced a nation of "creative" thinkers.

Most highly creative people are so because they choose to be.

Cross training can aid in encouraging and enabling people to return to their natural creative thinking abilities.

One form of "breakthrough thinking" has appeared to come from people with cross-training, "Jack (or Jill) of all trades master of none", multi-experienced careers.

Others have written that it the knowledge of self combined with the knowledge of process rather than simply content that enables someone to produce breakthrough thinking.

One flaw is that it takes extensive knowledge to recognize a "breakthrough" in thinking and see its relevance.

An aspect of my creative training and writing is that "everyone can have ideas, it takes experience and knowledge usually to turn them into solutions".
