I also have some days when no ideas come. I believe it's also good to accept that and not put ourselves too much under pressure when that happens. I learned that it's difficult to be creative when under pressure.
Breathing and meditation also allow us to get into the parasympathetic nervous mode that acutally helps us to think. So your technique is very appropriate.
Thanks a lot for your comment!
Yes, I agree. It all depends on what method we feel most comfortable with!
