This could be shortened to "success does not belong to the skillful, for time and chance befalls all" with no meaning lost. It's self-indulgent fluff. Meanwhile, Orwell's actually adds more to the statement - much better signal to noise.
> To every thing there is a season, and a time to every purpose under the heaven: a time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted; a time to kill, and a time to heal; a time to break down, and a time to build up; a time to weep, and a time to laugh; a time to mourn, and a time to dance; a time to cast away stones, and a time to gather stones together; a time to embrace, and a time to refrain from embracing; a time to get, and a time to lose; a time to keep, and a time to cast away; a time to rend, and a time to sew; a time to keep silence, and a time to speak; a time to love, and a time to hate; a time of war, and a time of peace.
That could have been said in less than a quarter of the words the author expended on it. But something of the style would have been entirely lost. He wasn't trying to be succinct, he was trying to repeat the same concept over and over until it sinks in.
Non est salvatori salvator,
neque defensori dominus,
nec pater nec mater,
nihil supernum.
No rescuer hath the rescuer.
No Lord hath the champion,
no mother and no father,
only nothingness above.
I find this one profound, and it's given me a lot to think about over the years - in situations ranging from asking what our place in the universe is, to doing the "right thing" (and deciding what "the right thing" even means to yourself), or standing at the helm of some team or project, knowing that judgement call is yours alone and there's no authority or higher power coming to swoop in and give you the answer or authoritatively judge your decision can be simultaneously liberating and terrifying. The use of repetition works incredibly well in my opinion and it still gives me chills to read it.
