A few months back I wrote here that if you have an idea you should write it down. Later someone said to me he had notebooks full of ideas, but had never developed any of them further. His notebooks were like places where good ideas go to die.
Last Thursday I went to my last graphic design class at Central Saint Martins and at the end of the class our tutor urged us to keep sketchbooks and fill them with ideas. And to make sure we kept those sketchbooks forever. Because sketchbooks (or notebooks - same line of thought) is where ideas go to wait. That’s the spirit.
