Optimistic or hopeful non-fiction

For 2026, I’m trying to get into a more positive headspace and also read more non-fiction.

I would be very grateful to hear your most optimistic, positive, or hopeful non-fiction recommendations! It could be someone overcoming adversity, solving a problem, making an amazing discovery, or letting their readers know that the world isn’t quite as gloomy as it seems. I would also love to hear about non-fiction books you enjoyed that were funny or entertainingly written.

I’m not generally a fan of celebrity memoirs, but I’m open to any other types of non-fiction. Thank you very much in advance and happy new year!
