I love the way changing how we think leads to all kinds of new ways to do things, and at this time of the year, as the days start to get longer, I want to celebrate a few of breakthroughs I noticed this past year. As well as some older ones I have always treasured.

The first one comes from a retired farmer in the US state of Georgia, who appears in a video made by an Atlanta tv station, 11 Alive, a few years back. He had farmed all his life, which meant that at retirement, he had no savings to fall back on – just his land. And that land was now home to solar panels. He was now growing sun.
