When you are not separate from the creative process, time ceases to exist. You might start to feel tired and suddenly realize that much time has passed. It isn't necessarily a happy time - and may be very difficult to start if it is a job or an obligation. But if' you start with all the concrete needs and proceed in a thorough way - the creative process will take over and you will forget whether it is work or play. Working in the here and now is one of the most uncontaminated ways to work.
