There are days when you can only grab a moment; those moments are not always quiet. The words can then serve as a focal point, a lull from the chaos of the day.
This idea applies to any craft.
But we feel the need for perfect conditions. These conditions, many times, prove as elusive as perfect love; the best we can hope for is getting as close as possible. If we do, we are lucky.
It is imperative that we move towards the goal, however slowly it may be.
