Although I have not been able to discover any written confirmation of it, I believe, since the beginning of time, when Man wanted to build something for himself he or she chose the best materials available.

 

If a shelter was desired then a nice rock cave would be favoured over a hole in a tree stump or a lean-to made of tree branches. If a fire was desired then dry sticks would be favoured over wet rocks. Etc.

 

Similarly, our ancient ancestors learned some cave-people were good at some things while other cave-people were good at other things. Over time, for example, some cave-people became makers of arrow heads, some became makers of wheels, some became gathering experts, some became hunters of land animals, and others became hunters of fish.

 

Later, specialization leapt to new technological heights. Some of the cave-people evolved into doctors, engineers, abstract painters, astronauts, and sales folks.

 

While all these changes occurred, people built on strengths and failed when they tried to build on weaknesses.

 

Now, in the 21st Century, we find our education systems and our businesses so developed we occasionally forget the lessons of the past.

 

Particularly, we forget people weaknesses don't build.
