"I spent a lifetime learning to draw like a child." Picasso
This is an interesting post from Thomas King about the complex nature of simplicity. Picasso's point about spending a lifetime learning to draw like a child seems important for web designers too.
The hardest thing to do is do less. The hardest mind to recover is the exploratory mind, the mind before judgement. When we recover the playful mind, the simple easily rewarding routine of play, our designs run free like Picasso's bull.
