I actually wonder a lot about this creative imagination of people that makes them discover, invent or create something new. Last month I was involved in some research work and I realized that whatever we think of doing as new has been well researched and written about numerous times in the past. Doing extensive research about any topic reveals that and this has given me food for thoughts. It is actually very disturbing to think that we are lacking greatly in the capability to think both critically and also creatively now.
