According to John Cleese, creating certain conditions makes us more likely to produce
open-mode thinking (i.e., where creativity occurs):
Space: Seal yourself off from distractions and the usual pressures to perform; create
an oasis of quiet for creativity.
Time: Create that space for a specific period of time, and tolerate the racing thoughts
and anxiety about the practical tasks you need to do outside your creative space
(eventually your mind will quiet back down again).
Time (again): Ponder solutions to a problem for as long as you possibly can —learn to
tolerate the unease and discomfort that come from not having solved the problem yet.
Confidence: You can’t be “spontaneous within reason.” Don’t cave in to the fear
of making a mistake because in the creative “open” mode mistakes don’t exist.
Humor: This takes us from closed to open mode more quickly than anything else can.
