Do you agree "what may go wrong, will go wrong"?

This is "Murphy's Law." Many who embrace this are often looking for something to go wrong and focus their attention on disastrous outcomes.
I am an optimist.
I don't necessarily believe if anything can go wrong it will go wrong.
There is a positive to every situation and therein exists an opportunity.
This statement is taken to the extreme and is the mantra of the pessimist.
If you look hard enough you will always find something wrong.
The opposite would be that there is always an opportunity in every situation or as some would say a silver lining in every cloud.
It depends on your mindset.

i agree on some times but not always

Not always.. but sometimes yes

I agree that what may go wrong , MAY go wrong , but NOT necessarily WILL go wrong .
In other words , if a thing wasn't meant to be , then it'd not come to be , & , vice verse .
Now , this brings up .
to my mind , the following two crucial issues , the first of which is that nothing is set in stone , in the sense that anything could be changed , & , consequently , could go south ( wrong ) , which is the exception , or , simply , it could go right , which is the the rule .
The second of which is that there are exceptions to the " Set In Stone " Principle , & , they're things that can NOT be changed , affected or influenced in any way , shape or form .
This includes , but not limited to , ( The Passing of Time as in the Time since it's beginning up until it's ending - Aging or Getting Old - Death , & , the idea that every thing has it's beginning & it's ending etc...
) .
Nonetheless , the question in of it self is philosophical & metaphysical in nature , meaning it has multiple dimensions attached to it , or , it can not be answered only from one-sided perspective , other wise it'd be a lop-sided answer .
Some people , & they're many in this case , are religious in practice & in concept , so their answer would be utterly & entirely formulated within , & .
according to their beliefs & convictions , keeping in mind that they could be strong believers in Science too , & , they'd see NO contradiction between the two , none whatsoever .
Others , would take a different route , such as the Science-Based Path .
Now some of the Science-Driven People can be actually bifurcated to two categories , the first of which would see no conflict or contradiction between Science & Religion , & , would use one to complement the other in their answer to such questions .
This Group is somewhat different than the " Religious In Nature " One , in the sense that the Latter would use Science to back-up & fortify their Religious Narrative , meanwhile , the Former " The Science -Driven People that'd see no conflict or contradiction between Science & Religion " could use one or the other to back each other up in no particular order , but sometimes , would use Religion to Back-up Science .
The second of which would totally drop Religion from the equation , & , would only go down the Science-Oriented Road .
Some would describe this second class as an Atheist , Agnostic , Agnostic Theists .
or simply Non-Religious , that sees no role , whatsoever , for Religion in Science .
So , depending on the answerer's complete & total lump sum of mind set , mentality , level of Education , Religious & political affiliation , & , sometimes any pre-conceived ideas , whether they're benign or malignant & prejudice in nature, an answer could be provided to the asked " Do you agree "what may go wrong, will go wrong"? " question .
( ...
& That's the way it goes ) .

what may go wron can go even better most of the time since life is all about learning from mistakes

i don't think that eventually it have to go wrong we can solve our mistakes and make things go right and make an effort to make things go in the right passes again and in the end we have to learn to try from the beginning make things right and think wisely in what we are going in.

Maybe, but this is not always the case most times. As much as possible one must try their possible best to avert the wrong or prevent the wrong from happening.

not necessarily, with good management control to keep to address thing proactively, wrong thing are seen and corrected in advance.

Not agreed.just It produces more challenge, "when there is a will there is a way"

i do not agree.
within the hospitality industry and more specifically the event industry, plans are always changing.
its up to you to keep a positive energy and ensure that should something go wrong you handle the situation calmly and to the best of your ability.
the more positive energy you put in, the more positive results you will receive

as long as a person understands how to handle situations constructively and does have the know-how in their respective field then there is always a solution to a given problem ergo avoiding or minimizing collateral damage in the process.
