I was reminded of this bit of wisdom by Jesse Breytenbach.
What my art teacher taught me: Make Mistakes.
When doing creative work – whether in the planning stages or in execution – don’t grip the steering wheel. Hold on with your fingertips and guide the process, allowing unexpected things to happen. Skill is in recognising happy accidents and making the most of them. A unexpected line may suggest the curve of a back, the turning of a head in a way you could never knowingly have contrived. Paint splatters, unexpected colour combinations – accidents can breathe life into your work.
