I am speaking for myself when I say creating comics makes me wiser.
I find that it's one thing to write well, another to draw well, and even more challenging to do both well together seamlessly and simultaneously.
I pay more attention to the details in life, both visually, emotionally, mentally and socially what makes people tick, cry, fume, laugh and downright puzzled. I record fascinating ordinary conversations and sights. I organize my memories differently. I have with me not only my own, but so many others. I collect experiences.
I desire to understand human development, how the relationships we create with one another forges such a diversity of personalities, how we physically age and keep our youthfulness. I desire to understand larger systems at work, institutions, governance, criminal, legal, environmental and ecological. I desire to be open to different ways of beings, their belief systems, their culture, their history, their language and traditions. I wonder more.
Once I understand more why people are idiots, why they suck, why they're kind and why they're so much more talented than me in so many different areas, I feel less resentment, less jealousy, less anger, less pity, less fear. It's that understanding I want to communicate.
There is some information words convey very well that pictures can't. There is some information pictures convey very well that words can't. And I love the magic of a comic that puts the best of both worlds together and communicates with more clarity than each world apart (and cringe at the worst of both worlds put together).
Of course, the web, animation and film adds yet additional dimensions to how the message is produced and consumed, but I've always loved the silent contemplative nature of reading at your own pace.
To do anything well makes one wise, because to do something well requires one to wonder more about the world.
For me, I want to write and draw comics well.
