Art is freedom

I am also in the position to create something, but I think artists are free because they don't choose their customers. Although it may sound strange, we professionals actually choose our customers. However artists don't need to choose their customers, and they just create and accept their observers. I think it is their freedom.

The greatest inventions of mankind

I think that the wheel is one of the greatest inventions of mankind. The activation of land transport with the wheels has led to improvement of our life. However, floating transportation, for example drones and linear motors etc, will be developed then wheels might end their roles in our history.
