John Cleese - Creativity

Short summary:
1) Creativity works for a large part in the sub-conscious brain, for example when sleeping.
2) Creativity is hindered or stopped when disturbed by an outside event.
3) To foster creativity create boundaries of space & time to work undisturbed and initiate the creativity.
4) To know how good you are at something requires the same skills as it does to be good at that thing. Which means that if you are absolutely hopeless at something, you lack exactly the skills that you need to know that you are absolutely hopeless at it. A teacher who lacks creativity often undervalues the creative work of a student, a manager is likely to take credit for the creative input of an employee.
