Please take care when you try the “morning pages”-exercise suggested by Cameron. It is similar to the method of “automatic writing”. According to psychology professor Robert Boice, the method gained ill respute for being “possibly addictive and […] potentially destabilizing”. (cf. Robert Boice, Professors as Writers, p.51). Another downside of extended spontaneous writing is that it usually does not generate a lot of useful text, but it can certainly help getting into the ‘flow’. Boice recommends a short session of 5 to 10 minutes, before advancing to what he calls “generative writing”, which is basically spontaneous writing with a goal or theme in mind, but without stopping to edit mistakes.
