Life is too random to balance out every time.
As a rule, we have to make use of the life span as fully as possible. Even if the life span is the same, its use and impact vary. It is in the notice of all of us.
All things are not happening to keep us happy and prosperous in all phases of our lives on this planet. Uncertainty is a common factor for all of us, regardless of our class or region. 
We are planning and performing well, but without claiming the outlines of end results. Simply put, life is random. 
Here, our ability to move forward plays a dominant role. The influence of background, education, and facilities is limited. All individuals are different, particularly in their characteristics, and it is also reflected in the scale of their performance.
It is evident that anything may come into the life of any individual, good or bad, at any point in time. The wisdom of the situation demands that this factor be taken into consideration, but nothing needs to be withheld in the name of uncertainty. 
We go out despite knowing that no moment is free from risks. Working in the shadow of risk boosts confidence, apart from getting the desired result. 
People are wandering in dangerous landscapes, and the majority of them have brought many new things for the benefit of the human race. 
Accept the realities and continue taking further steps to unearth new realities. We have to create conditions and not surrender, even if tough situations arise. 
Let life behave abruptly here and there, but be tough to shape things right every time.
