Creativity happens in the present moment

Basically, being present for our experience, in the moment, what ever it is—good, bad, indifferent. We are training to be present in our lives. This is the only moment we have.
What creativity requires is a flexible brain. A brain that can go from right to left depending on what we need.
It's strengthening that sort of flexibility and openness and fearlessness of our minds. We are training and we do that by noticing and coming back, noticing and coming back. It's like reps.
If we are missing our present life because we are so caught in thoughts about the past and the future, if we are living so much in the future and so much in the past and not in the present, then we are missing our life and we are missing lots of information about what's true for us.
