1. Here I take some notes of my work. 'Here' is confusing. I think you meant, "I am taking some notes of my work" 2. There are still many places that I've not been to yet. It's correct, though a little formal the way you've done the contractions ("I've not been") In conversation people would tend more often to say "I haven't been" instead of "I've not been". "There are still many places that I haven't been to yet." 3. I write down everything in my life journey. It's correct.

@James Holloway Thank you! I was trying to compare life to a journey. Is there any word or phrase?

@Daniel Thank you! The last one I was trying to express that I write stories about what happened in my life and comparing life to a journey.

1. I take notes here, in my journal/diary/notebook etc. 2. There are still a lot of places I've not been to yet. (to be honest, many is also fine) 3. I write down everything in my life journal* (I think you mean journal here right?!)

Hey I’ll try to help you with the first and second sentence because I didn’t understand the last one. In the first sentence I understand that you are talking about the place where you take notes, a tablet or a notebook por example. If it is that way I consider you should write something like: I take some notes of my work here. The second sentence have pleonasm (“still” and “yet”) so a better way to write it can be: There are many places I haven’t been yet.
