The reason you strive upwards but achieve nothing is that you are not ruthless enough.
What is the essence of ruthlessness?
It is not like Li Shimin, who shot his brother with an arrow to become emperor; that is a narrow understanding.
The essence of ruthlessness is to pursue the utmost efficiency despite all difficulties, which means you have to be a radical, willing to work tirelessly for your ideals.
This means you cannot have too strong a sense of right and wrong; as long as you do not violate basic social morals, you should do whatever works.
This means you should not be too limited by your background; if your family of origin has caused you too much harm, you must bravely break free from the cage and boldly take a chance.
This means whenever you smell the blood of a big prey, you must shamelessly rush up to snatch the food.
Those who accomplish great things do not get entangled; the essence of being entangled is not being ruthless enough. Ruthless people always overlook the trivial details.
What they see is the essence of things; they know which link can lead to a direct turnaround, and they will work hard in that link!
Those who never dawdle with you must strive to move up; they will always have to compete with others and will always be criticized.
A compassionate heart can win you an audience, but a wolf's ambition can help you win the championship.
