Nitpick - the point of parentheses, as used in the article title, are to add optional extra context without being required to make the sentence complete. The sentence "Reflections on 1 year of become successful on YouTube" isn't complete. Either remove the parentheses (thus making those words part of the title), or consider a different sentence structure.

I love this nongrammatical/idiomatic use of parentheses actually. Language is a tool, and its rules can be just as powerful when violated as when upheld.

In this case they convey a subtext you can’t get as gracefully by being a slave to syntax— that the author hoped the post would be about how they did achieve success, but that didn’t happen, forcing the parenthetical qualifier. I don’t think another treatment would express that quite as well; you can almost feel the wince.

you’d normally use square braces [for this kind of thing]

Nitpick to your nitpick:

You've offered a linguistically prescriptive interpretation that ignores nuance and flexibility of language.

While it may be the case that the canonical "point" of parenthesis is what you've described, the purpose only remains for as long as we culturally accept that definition.

The usage of parenthesis as an aside to indicate a certain emotion somewhat playfully is not only acceptable, it's entered into the cultural zeitgeist. We all understand the meaning. The sentence is complete -- regardless of the rules you've cited -- because the reader doesn't eliminate the parenthesis from their context like a robot, and we have a common understanding of what the aside is trying to communicate.

I appreciate the nitpick. I am certainly not the strongest writer but hope to write more articles in the future. Thank you for the feedback.

Probably become=>becoming whould help

"Reflections on 1 Year of (Trying to) Becoming Successful" isn't correct either.

OP has been "trying" for 1 year, not "becoming" for one year.
