an easy way to increase creativity

All you need to do is distance yourself from the situation:

According to the construal level theory (CLT) of psychological distance, anything that we do not experience as occurring now, here, and to ourselves falls into the “psychologically distant” category.…According to CLT, psychological distance affects the way we mentally represent things, so that distant things are represented in a relatively abstract way while psychologically near things seem more concrete. Consider, for instance, a corn plant. A concrete representation would refer to the shape, color, taste, and smell of the plant, and connect the item to its most common use – a food product. An abstract representation, on the other hand, might refer to the corn plant as a source of energy or as a fast growing plant. These more abstract thoughts might lead us to contemplate other, less common uses for corn, such as a source for ethanol, or to use the plant to create mazes for children. What this example demonstrates is how abstract thinking makes it easier for people to form surprising connections between seemingly unrelated concepts, such as fast growing plants (corn) and fuel for cars (ethanol).
