“Art & Fear” (David Bayles, Ted Orland)
Just over 100 pages but filled with insights and plain-spoken pragmatism about creativity and work. The adage that the difference between the master and the novice being the difference in the amount they discard translates to work, to making stuff.
They even cite one of my favorite anecdotes about the pottery class where the grades were assigned to one group based on the number of perfect pots and to the other based on the sheer volume or weight of work produced. You know who ended up with the better work product, if they had to show just one piece: the former group often ended up with nothing, while the latter learned about themselves, their craft, and their materials.
