John Cleese has set up five thesis how to create creativity

He sums the main factors short and sweet together. Still, it doesn´t really lift up because he leaves open where the ideas come from. Cleese says "they do not come from the laptop".

1. Space

You can’t become playful, and therefore creative, if you’re under your usual pressures.

2. Period of Time

It’s not enough to create space; you have to create your space for a specific period of time.

3. Time

Giving your mind as long as possible to come up with something original, and learning to tolerate the discomfort of pondering time and indecision.

4. Confidence

Nothing will stop you being creative so effectively as the fear of making a mistake.

5. Humor

The main evolutionary significance of humor is that it gets us from the closed mode to the open mode quicker than anything else.
