If you have a core belief that ‘I am never good enough’, which leads you to put 100 per cent effort into everything that you do, try to put slightly less effort in and see what happens. For example, if you spend on average one hour cleaning the kitchen, try spending three-quarters of an hour; again, you could predict what you think will happen. Then see what actually does happen. Has anyone noticed? Is the kitchen really that much different? Did you have more time for relaxation?
