Creativity and Time

I am often struck at how creative ideas or concepts evolve over time and how long it takes.

I find that I can take a design and product to a point I am happy with. Set it aside for awhile and then come up with an iteration that reduces cost to the customer. When looking back I always say to myself it seems intuitively obvious, why did I not see that sooner?

So what to do when faced with such a quandary? Obviously Google the problem.

I found two interesting sources.

The first is a PBS Note to Parents about creativity in kids.  Actually does a good job of explaining creativity and how to identify it in children.

The second is an on line course in critical thinking at The University of Hong Kong. More in depth and up to date.

I have started to delve into the second link. It takes a little time for me to absorb and process this type of material.
