Not that I want to overemphises that latter fact, but I must say that it really makes me feel shivers and smile proudly - we need this kind of examples to inspire us. A quote from BBC world:
The Star Trek fan, who spent her early childhood in pre-revolutionary Iran, has spoken of the nights on the balcony gazing at the stars and a longing to become an astronaut.Imagine that! And now she's in space, blogging away, after making it to Fortune magazine's "40 under 40", ha! Kinda person that makes me want to achieve something too. Being an example to someone else and make a positive impact on them.
