More and more people seek help to their personal, everyday issues through bettering their environment, including homespace, that obviously influences the way we think, feel and act. Something made by hand carries a different force and effect than the colour and material of a random couch or table. Many artists are studying art therapy to make the best for humanity, and earn their own plus points for it, as well. That is just fair.
...a more colourful place to live in. Painting can be considered such a small-scale thing, a decorative element in your room, really, but what's possible to do with it, is grand - the change it brings with it, the time it lasts, the quality it brings to your space experience, is otherworldly.
