I think someone said before that art speaks where words are unable to explain. There are so many things that can trigger inspiration, and any form of art can do that easily. We are surrounded by art on a daily basis, but not everyone realizes that. The cars you see everyday on the road are structured beforehand by an artist, it's a work of art. That fancy coffee table you use, that could be considered as an artform. So use your surroundings if ever you need some kind of inspiration. They're everywhere.
