If you want to develop your ability to enter the creative zone at will, you should know that there are three conditions for a really effective hypnotic trigger:
Uniqueness – it should be something (or a combination of things) you don’t associate with other activities, otherwise the effect will be diluted.
Emotional intensity – the kind you experience when you’re really immersed in creative work.
Repetition – the more times you experience the unique trigger in association with the emotions, the stronger the association becomes.
So to fine-tune your daily routine for maximum creative magic, make sure the key triggers have these qualities. For example you might want to save a particular album for listening to while you work, or be careful not to use the same notepad for sketching ideas as for your to-do list. And when you have a particularly good day, make a note of something in your routine for that day, that you can associate with the emotional state – and use the same trigger the rest of the week.
