偶然
In politics, nothing happens by accident. If it happens, you can bet it was planned that way.
No man knows, or ever will know, the truth about the gods and about everything I speak of; for even if one chanced to say the complete truth, yet one knows it not; but seeming is wrought over all things.
Success is not accidental, but achieved through continuous effort and persistence.
Success is not accidental, but inevitable.
Success is not accidental, it is the result of effort, persistence, learning, and sacrifice.
