The best job in the world )

It is hard to choose a particular job, even though we can immediately namention dozens: of prestigious, well-paid, a jobs everyone dreams of.

mention: refer to (something) briefly and without going into detail.
"mention" is understandable, but doesn't strike me as very appropriate here. Allow me to suggest "name".

And sSometimes it works out, but there is one more perspective which relates to the correlation between a particular person and a particular job, when we say that they are offmade for that job, even if such a job doesn't bring a lot of happiness to its ownerthem.

(1) work out: have a good or specified result.
(2) be made for something: be exactly suitable for something.

AndWhen discussing the best job, we should not forget about the relative characternature of it,: there is no job without the man.

(1) "character" is understandable, but in my experience, it is moreso used in relation to people or tangible inanimate objects. Jobs, however, are an abstract concept, in which case "nature" is probably more appropriate.
(2) The use of the colon is expected here, since you're supplying an explanation in the same sentence without the use of transitionary conjunctions such as "since" or "because".

And the man or woman is important, and important is their attitude, in our case, their attitude to the job.

And then wWe can say that any job could be the best job ... Ffor some of them.

"for" should only be capitalised if it's the start of a new sentence, which it is not.

So then, the question should be rather put nonot be about the best or worst job generally, but (rather) the best andor worst job for someone.

A comma break after "so then" might be good.

In such a case, the nature of our perception of 'the best' or, correspondingly, 'the worst' job, slightly shifteds from outer characteristics, as attractive as they ever could be, to a more specific inner perceptionmay be, to something more specific and personal.

(1) It should be "shifts" and not "shifted". The past tense doesn't make sense here, since we're in a hypothetical ("In such a case").
(2) While I knew what you were trying to say, "to a more specific inner perception" is a rather awkward and unnatural expression. You can consider my suggestion.

And tThen, even a job which is not considered to be not socially respectfulable could bring a lot of joy to someone.

(1) Moving the "not" in front will sound more natural.
(2) respectful: feeling or showing deference and respect.
respectable: regarded by society to be good, proper, or correct.

I recently read about a man who was a journalist whoand interviewed a celebrity, but after being fired, he started to work as a driver of a garbage truck and. He found peace and happiness because he wanted to be in the open air and do physical work without the engdless stressful searching of/for a new topic for a new article.

(1) I replaced "who" with "and" to avoid repetition of "who".
(2) I broke your sentence up into two, because it's a little too long.
(3) You need a preposition between "searching" and "a new topic". Both "of" and "for" are okay here.

So, then the question should be rather putbe, not the best or worst job generally, but the best and worst job for someone.

And then even a job which is considered not to be not socially respectful socially could bring a lot of joy to someone.

I just added a full stop, since the sentence was getting too long.
