The reason for the instability in a person's life is his lack of control of his soul. A person's soul is every time ready to roam here and there, thinking continuously of the ineffective times, wasting time on unnecessary things, indulging irrelevant fears and behaving stupidly each time in spite of knowing all these things. Isn't it right friends? Our instability in life comes from the in-stable state of our soul. So, what matters most is conquering one's soul without fearing the uncertainties of the future.
This is because we all get one life. And we all also know that happiness and sadness come in pairs. So, if we know it completely that if we are having bad times, they will pass away anytime soon and vice-versa if we are having good times, we may face bad times in the near future. Because we cannot be happy all the time and also we cannot be sad all the time. One should realize that no matter how difficult times are, the soul must always win. Like if we lose our soul, then we lose everything.
Now, the point is what is the main reason which makes people fear everything. And the answer is "Change". According to me, what people fear the most is the change. It is always hard for people to embrace change, especially in the situations where they get too close to somebody or something. I am saying this because even I am afraid of change the most. Although, I know that things go for better. But still, change scares me large and sometimes to some extent.
Conquering one's soul is an art and obviously, not everyone is born to become an artist. Some are born artists, some struggle to become, and some struggle and fail. What I want to say is, if you are going ahead in life with the unstable state of mind and soul, please stop there. Because in the end, what matters most is the peace of mind. One should learn the art of conquering one's soul. If he gets there, he gets everywhere and gets everything he wants.
