Where do new ideas come from?

I think new ideas come from inspirations.For example, when little Leonardo Da Vinci was in the yard on a cold wet stump looking at all of the animals and the blue sky.He suddenly he got an inspiration and took out a paper and pencil.He started to draw them,soon he drew them everyday and that is how Leonardo Da Vinci developed his love for art.He grew up as a great painter,inventor, and scientist. He was unique in his own special way. In many people’s opinion he was one of the best artists in the world.The little boy who once drew animals later drew one of the best paintings of our time.
