From Ngan's list on that get you thinking.
Known as the Warren Buffer of Japan, Wahei Takeda was a billionaire and investor living in Japan that passed away in 2016. He had a philosophy of life that built upon the concept of gratitude. A mentor of mine met and studied with this man, and he shared that every day, every day, he has a practice of giving 1,000 gratitude. Not figuratively, but honestly, living in a state of gratitude. I have tried this and go back to the practice of giving 1,000 when I need to shake myself out of a rut. It’s transformational, and it’s hard. It usually takes me three days before I can get to 1,000 and the last 600 pushes me to see beyond the surface. Give it a try!
