I'm upset sometimes. So I research how to calm my mind on websites. And then I found "HO'OPONOPONO" that is Hawaiian culture. When I was changing jobs, I did not have any time to travel. I went to Hawaii to seek the culture. But I couldn't find this on my trip. Now, I actually know just few phrases about this. "thank you." "I'm sorry." "forgive me." "I love you." It will help my mindset... It's like a joke. But, I like those phrases:)
