Corneille's painting again

I read in the Volkskrant that Corneille is painting again. I'm curious how painters work and learn and become masters. Corneille says he detests inspiration and just starts working, in the same way a child would paint. Starting with a stroke of paint and adding new ones. When he was 20 years, he formed a three-manship with Appel and Constant, as he explains, this followed from forming the group of the 'experimentelen' of painters and poets. The three-manship lasted only 3 years, as they prefered to continue as individuals. When they met, they did not talk about each others work, but they did talk about paint and women. Nevertheless, they did monitor the developments in each others work.

I think what intrigues me is that in the end, the basis of their development process is very individualistic. They do observe each others works, but don't discuss it. I wonder what this means for communities of practice, whether individual development trajectories are not the core of communities of practice. So we should maybe be more modest about the community part, and recognise that the basis for practice is very individualistic.
