1. Relaxing music is best. Not as you would think, intense music. I listen to classical music, folk music most of the time. ANYTHING CALM. Let your spirit be calm, not excited.
2. Believe in yourself. Not too much, and not too little. The craftsman's edge is the humbleness, and critical eye, but also you have to believe in magic. Always be aware of how you are feeling-- know your nature-- curb yourself if necessary, urge yourself if necessary! Make a leap.
3. Good enough. Don't be perfectionist, you won't be able to move on. Just do "good enough". You'll get in the flow then, and when you are in a higher flow, will go back and fix easily what you now can, naturally.
4. Listen, listen, all the time. Otherwise, what is the point? I often find myself knowing I should do one thing, and ignoring it for a minute-- but a minute later I change it, as I know I should listen.
5. All the time, you can work on your discipline and patience. If you are about to work, but have to do the dishes first, but feel impatient-- do the dishes! After all, that is how you will work.
It's worth it. After all, what could be better than being the universe's pencil?
