★ To everyone who feels "busy but not fulfilled," "I had time, but in the end, I didn't do anything all day," or "Nothing changed this year." Having a fulfilling and good day is very easy. That's because you don't need every single one of the 24 hours to be wonderful to feel like "it was a good day." ・The two hours I spent drinking with friends were so much fun. ・The two-hour movie I watched today was incredibly stimulating. ・I received a happy letter from my child. ・I came up with a solution idea for a problem I'd been thinking about. ・I was happy to guide someone who was lost. In fact, a fulfilling "good day" can be obtained with just two hours like this. Some can be obtained in 10 minutes or even 1 minute. If you have just one "best moment," the entire day will change for the better. Having seen many happy entrepreneurs, over 30,000 people, the author's conclusion is that "people can be happy if they have a fulfilling 2 hours a day." As many people feel, "Just having a two-hour drink with close friends at night makes the day happy," or "Just having a two-hour concert on the weekend makes the week happy," a fulfilling everyday life doesn't require every hour of the day to be fulfilling; it's enough to make just two hours the most fulfilling. This is a new perspective on "time x happiness," focusing on "committing to only the important 2 hours" instead of aiming to "increase productivity" to raise the happiness level in life.
