Interruption and distraction are the single most detrimental thing to productivity and creativity.
The finished artwork is hours, months, or years of work that is distilled into a single piece that you can consume in a moment.
For the artist to create requires empty blocks of time. Slabs of hours, uninterrupted and without distraction. A block of six hours is not the same as three blocks of two hours. What can be done in six uninterrupted, focused, free six hour block might be 25x blocks of two hours.
Smaller sporadic chunks of time are exponentially less valuable than the bigger chunks of time.
If you can reserve several large (90+ minutes) blocks of time in your day and block out the distractions your life and business will change drastically.
Slabs of time make the creative mind tick. In them you get lost and in them you discover the things that make you special.
