Defining Creativity

What is creativity?

in my opinion, creativity is the ability to create.
but this does not mean that creative people is able to make a pen out of nothing, no that would be magic, or maybe even godly power. what i mean by "the ability to create" is making a new thing, like the invention of door. yes door.

i think that door is a great idea, even though it is just a piece of wood, it gives you security, it limits your view, it's like a barrier or a shield from the "outside", and yet it is just a piece of wood (or steel, or maybe even glass). and you can go in and out through it, and if you don't want people to go in or out, you can just lock it.

this is what i mean by creative, the inventor of doors does not make door out of thin air, he uses a simple, everyday material and use it as a barrier, thus he "create" a door.

this is what i mean by creative, the ability to create something out of existing material, or even a new material.

and that is my definition of creativity, the ability to create.
