John Cleese gives a good lecture here on how to set up the opportunity to be creative. Not how to be creative, which he can’t teach, but how to set up an environment to let creativity happen.

His commentary also applies to trying to divide out creative-type-work time from bookkeeping-business time, which is difficult if you struggle with things like relative importance of art. (See also aftereffects of “Tiger parenting” and “Harsh parenting.”)

He also has some tips for PHB’s at the end, which you may find amusing.
