Getting started is the monster part of the battle of getting a project done.
Quick sketch backgrounds one after the other until you feel how feel how easy it is to let go a piece and seize on the next. Feel how your brain starts making connections between your desperate, fast breathless drafts.
Feel the empty space fill with a plan to next.
It works. Failing my florid prose, do this: put 20 minutes into starting something while bargaining with yourself a procrastination excuse worthy of a Hollywood Star.
Just 20 minutes.
