Where does art / illustration fit into the health/wealth/relationships framework

I am a visual artist and illustrator, and I am drawing humorous”life advice” cartoons, and want to specialise in visually interesting and engaging, fun worksheets, and offer drawing classes for coaches. I know this is useful and I get good feedback, but I am struggling with finding a convincing description / copy, and I suspect it is because I can’t pin it down to one of the three areas of health, wealth and relationships.
Do I have to promise “you’ll get rich if you learn to draw”? Or “Drawing is healthy”? Or “Connect better to your clients by using drawing in your presentations”??
Thank you!
