Intent increases with success and declines with failure, I went through a dry spell recently when I had a phase of unsuccessfully trying to WILD, I literally lost my 'I know I can'. This is why the more lucids you have and the more frequently you have them builds exponentially, you learn to access the neural pathways of 'I am a natural lucid dreamer' more easily each time and the pathways get stronger. I think that's what Silverbullet was trying to get across in his thread. He had 200 lucids in one year or something crazy, simply because he knew he could.
