“Playfulness is the hallmark of any great human activity; it inspires innovation and change, and it nourishes the mind as well as the body.” From The Think Big Manifesto by Michael Port.
The biggest killer to play is (fear of) judgement and disapproval. External and self judgements, the latter being the hardest to mitigate and manage.
The biggest thing any creative person can learn is to not need anyone else’s approval. “Ignore everybody”, as Hugh MacLeod says.
