"Confidence" is an uncountable noun. If a noun is not countable, it either takes "the" or no article. Most uncountable nouns in English are abstract ideas or concepts, like confidence, knowledge, revenge, spirituality, or perseverance. Uncountable nouns can also be substances like water, iron, or wood, or nouns that are made up of multiple parts like sugar, rice, or furniture.

In my office, I have to speak English every day at all times due to our shipbuilding business needing to be a global business expansion, even if ithere is in Korea. In my office, I have to speak English every day at all times due to our shipbuilding business needing to be a global business expansion, even if it is in Korea.

"Due to _________ needing ________" is an expression in English. It would also be correct to say "Because _________ needs ___________". "global business expansion" is a countable noun, so it either takes "the" or "a". "a" is used in this case because your shipbuilding business is a specific form of a general global business expansion.

When I entered into this company, every single day, I could not read explicitly the specifications and technical/commercial documentations due to my previous duty was not requiring med to use eEnglish. When I entered into this company, every single day, I could not read the specifications and technical/commercial documents due to my previous duty not requiring me to use English.

In English, entering something is always seen as going into it, so "into" is used. "Documentation" is a noun in English, but it refers to a general source of information and is uncountable. "Document" and "Document" refers to written documentation. Same as before, when using "Due to _______", the verb afterward (in this case, "to require") must always be in the -ing form. So, you could say "Due to my sister not wanting to leave..." or "Due to my company prospering..." And, also same as before, you could say "Because my previous duty required..."

When I enterstarted ato this company, every single day, I could not read explicitly themy duties did not require me to use English, so I never learned enough English to be able to read specifications and technical/commercial documentations due to previous duty was not required to use english. When I started at this company, my duties did not require me to use English, so I never learned enough English to be able to read specifications and technical documentation.

I think something is not being conveyed properly. If you never had to use English because it was not required for your duties, why were you trying to read specifications in English? I tried to fix it but I don't know if it's accurate. note: "documentation," especially "technical documentation," is strongly associated with computer code documentation/comments. Hope that's what you meant (I assume so since "specification," another software development term, is also in there)

"Smart" is a very general term and usually isn't used when referring to languages "as hard as jumping up" is not an expression in English. You could also say "English is a tough nut to crack" "Learning English is like pulling teeth" "Learning English is a Herculean task" "Learning English is a tall order"

"offline foreign friends" is countable and plural, so if it's not specific it doesn't take an article.

"except for making friends" makes it sound like you don't want to learn English that would help you make foreign friends "other than by" clarifies that "making foreign friends" is the METHOD of improving your English, and that you are excluding that method
