The creative habit is like a drug. 

The particular obsession changes, 

but the excitement, 

the thrill of your creation 

lasts.

The secret of life is to have a task, 

something you devote your entire life to, 

something you bring everything to, 

every minute of the day for the rest of your life. 

And the most important thing is, 

it must be something you cannot possibly do.

To know one thing, 

you must know the opposite.
