What is the most difficult thing to do, how many years does it take? How many years is the most difficult to take by 天風 231103

 I'll try setting the period to 4 years, 20 years, 30 years, depending on my preference. Which year is the most difficult? There are many things that can be said to be difficult. When it comes to studying for a qualification, it would be amazing if you could pass it in four years, and when it comes to marriage, the most difficult thing to do is to live happily together for 30 years. Surprisingly, 20 years old is sometimes the most difficult, and there are patterns where younger people are more physically active, such as sports or martial arts.

Why did I ask this question? Many people think that time is infinite. I'm still young, so I can't imagine myself growing old and dying. However, I feel a sense of crisis about what will happen if I don't make any effort and just continue living my life day to day. I still want to talk about this story with you. As a student, I want to be involved with everyone. See you soon.
