Yes, I do think happiness can be taught. The most important thing to keep in mind is that happiness is a state of mind, and it’s something that we create for ourselves. It’s not something that’s given to us by other people or by our circumstances.
One of the best ways to start cultivating a happier mindset is by practicing positive thinking. Just like anything else, it takes time and practice to develop this skill, but eventually it will become second nature. You can also read books or listen to podcasts about happiness and positive psychology, and attend workshops or retreats that focus on these topics.
