The Japanese village Ogimi is called the “village of longevity” due to the high percentage of centenarians. (If you want to know more, I recommend the book Ikigai-The Japanese Secret to a Long and Happy Life by Héctor García & Francesc Miralles).
“One hundred percent of the seniors we interviewed in Ogimi had a primary and a secondary occupation. Most of them kept a vegetable garden as a secondary job and sold their produce at the local market.”

As freelancers, these seniors can be our role models. As illustrator, for example, in addition to commissioned work, we can sell paintings and products, give local workshops, or offer online courses. There are plenty of opportunities, and who knows where and to whom the additional financial pillar will lead us?
