New Ideas- Where do they come from

Idea's come from everywhere. Experiences, inspiration and life everywhere or it can be out of the blue. You could be sitting around twiddling your thumbs and you get an idea. Like what Michealangelo once said "I saw the angel in the marble and carved until I set him free". It shows that you keep thinking about the new idea until you bring it to life. Basically idea's don't come from a certain place, They come from everywhere because the possibilities are endless.
