This informal essay is based on a presentation James Tanton gave at the Australian Association of Mathematics Teachers (AAMT) 'Why Maths?' Conference in 2019. It begins by offering two first steps to problem-solving that Tanton believes are key for finding success--and joy--in doing mathematics: (1) Be human! Have an emotional reaction to the problem at hand; and (2) Do something! ANYTHING! Tanton observes that brilliant and creative thinking often comes from just doing something in reaction to a challenge. Therefore, he provides five guiding principles for doing just that.
