Le Corbusier was a French architect. I just found a quote and I try to translate in English. It’s a good tool you can use to be creative (if you need to) :
When a task is given to me, I use to put it inside my memory, which mean I don’t allow myself to draw any sketch, for months. The human head have a certain independence : it is a box in which you can pour loose elements of a problem. One let then “float”, “simmer”, “ferment”. Then, one day, on a spontaneous initiative of the inner being, a click happens : one takes a pen, one gives birth on the paper. The idea comes out, the baby comes out : he comes into the world, he is born.
This is a great tool, and it can be mixed with other “common sense” plans (creative people know, for example, that they “work” in front of their blank page, but also that they get “ideas” elsewhere, walking in the street, washing the dishes or after making love). So, think about your problem and go talk to the birds, or bake a cake!
