The surface of the mind, sometimes calm and still like a stagnant pool; sometimes brushed by a gentle breeze, creating ripples; sometimes hit by raging waves, as if there were monsters lurking... The human heart is truly unfathomable, even to oneself.
Every time I go out and take a ride, I always like to sit by the window because it allows me to easily observe the ever-changing scenery outside. As the picturesque landscapes pass by, my mood changes accordingly. My mind is filled with endless thoughts, constantly jumping from one place to another... Actually, at this moment, I'm not really looking at the scenery, but at my own inner self. I think, compared to the external world, it is even more difficult to understand one's own mind. No matter how complex and ever-changing the world is, there are always patterns and rules that can be followed, to some extent, and can be predicted. But the mind, it is unpredictable. Because many times, you cannot know what it will think of in the next moment.
Even if you know everything about a person's past actions, thoughts, and future plans, you still cannot fully see through them. You still cannot completely predict their thoughts and actions in the next moment - or their reaction to events happening in the current environment. There may be certain patterns and rules in this (such as MBTI personality analysis), but not everything. Apart from the part that can be predicted, the rest is determined by inscrutability.
