When just your actions, movements and creations are the reason for someone else to create something new. It doesn't necessarily need to be purely fresh, it might just be an analogy to something else. When because of what you said someone else is finding happiness in his/her life again. When you as a person are an inspiration to somebody else.
It is possible that being inspirational is also connected with originality - that because of having your own style people tend to do things as you do because they see some kind of hope in your actions. Also this might have something to do with your values and being strong.
