Creative thinking is not a talent, it is a skill that can be learnt. It empowers people by adding strength to their natural abilities which improves teamwork, productivity and where appropriate profits. - Edward de Bono
Everyone is creative. It is a natural gift we are all born with that we actually have to be schooled out of. Watch young children at play and see how they naturally use their imagination. Consider their willingness to draw outside the lines and the way they don't judge what they are doing. They are "just" playing, having fun, trying different possibilities.
Play is a large part of what creativity is all about. Once we start playing with an idea or any creative form we then need to be open to the inspiration that will come through when our everyday mind is quiet or distracted by routine tasks like doing the dishes, driving our car, going for a walk, or taking a shower. At that point the bright idea or solution rises up out of the subconscious almost like something out of a dream and we need to write it down or intentionally remember it or like a dream image we will not be able to recall it later on.
One way to claim your creativity is to begin asking questions like "what would it take to solve this problem" and then don't try to figure out the answer or solution with your rational mind. Rather let it go and then just notice the thoughts or ideas that pop into your head during the day.
This can include the urge to turn on the radio where you hear a song or program that provides you with an ah. ha moment. Or you pull a book from the shelf and open it at random and a bookmark falls out with a quote that gives you another idea. Or we wake up in the middle of the night compelled to start writing. We are all different and creativity speaks to each of us in different ways. Part of being creative is learning what works best for you.
Another benefit from learning to work with your creativity is that we naturally experience a sense of joy and excitement since we are operating in an expanded state that feels really good. Start playing and see what happens.
