This is Sea. It is always moving. It is always changing. In the open sea there is nothing, only water(blue, grey), skies(blue, grey) and the whites of wave crests and sails. There are promises of exotic lands that you are going to see (stains of other colors). But those destinations are not the ends, they are means to motivate you. The journey is the ends. The purpose is to challenge yourself, to see if you are capable to do it.
