Departure from Europeanism and Return to Japaneseization Theory --- Repent --- Accept "Everything"
A lot of things happen in life. If there are fun things and events to get, there will also be things you don't like and things to lose. There may be some things that just don't make sense. However, it is important to accept “everything” that happens in life. Everything that happens in life is "good", and it's what feeds your own mind to grow.
If there are fun things to do and events to gain, many people will think, "It was good." On the other hand, if there are bad things or bad events, it will be difficult to think that it was good. In life, you want only fun things and events to gain, and you don't want bad things and events to lose. Also, you don't want to remember bad things that happened in the past. You get angry every time you remember an event that you don't agree with.
In fact, it is not something that can be simply defined as "good" or "bad" that happened in life. Even the same event can be "good" or "bad" depending on how you look at it. In short, if you were able to learn from it and get hints and chances to grow your mind, that's a good thing.
Surprisingly, people tend to grow more easily when they face troubles and difficulties. If you only do fun things, your heart will stop growing.
Perhaps, if you change your perspective and review the events that make you angry and unconvinced, you may find hints for growing your own mind.
See life as a stage for your own spiritual growth and accept EVERYTHING that happens in your life. And think about what you have learned from them so that you can think that everything that happened in your life was good.
