If I have homeworks to do for instance, I would pour myself a cup of tea, listen to some chill music, set a library background on yYoutTube, and then do the work.

"Homework" is an uncountable noun in English, so it doesn’t need to be plural.
"Would" is unnecessary here; the present tense works better in this context to describe your usual routine
"YouTube" is the correct capitalization.

I think tThe surrounding environment really helps tome engage with the task.

"Environment" makes the sentence clearer, and "helps me engage" is more natural than "helps to engage."

Secondly, I'm either setting set a timer or trying to reach a certainspecific goal.

it would go as such : For example, work for 45 minutes and, then havtake a 10 -minutes break, or read until this page/complete X amount of work.

The phrase "it would go as such" is a bit awkward, so I rephrased it to "For example" for clarity.
"10 minutes" was changed to "10-minute" as a compound adjective, and the sentence was restructured for smoother flow.

I believe what matters the most is consistency and discipline.

"The most" is not necessary; "what matters most" is the more natural phrasing.

OPTION A: Firstly, I try to romanticize the taskenvision the task in a positive light.¶
OPTION B: First of all, I try to see the task in a positive way.

I think theCreating such a surrounding really helps to engage with the task.

MY GUESS: Secondly, I'm either setting a timer or trying set a timer to reach a certain goal.

it would go as such :For example, I might work for 45 minutes and then have a 10 minutes break, or read until this page/complete X amount of work. Another possibility is to continue working until a set of work has been completed. For example, I might continue reading until a designated page has been reached.

Ultimately, I don't think motivation should be what we are looking for to complete tasks.(MEANING UNKNOWN)

Some days themy motivation simply isn't there, and there isit seems that nothing one can dobe done about it.
