New year's resolution in 2018

My new year's resolution in 2018 is to be active and to output  implement what I learn, experience, and think.
I moved to London from Japan last October, and I've been living in London for about three months for now. At During the first couple of months, I had difficulty to get used getting used to to my new life in London. For example, when I go went to a supermarket to do the shopping, I could not understand the difference between "4 for 3" and "4 for £3". I was confused to see that advertisement of for beer.  misunderstanding "Can I get four bottles of beer just for £3? Although a bottle of beer costs £2?! Is London helpful and supporting big families or promoting having home parties?!"... Now I understand the difference and I'm good at shopping here, but such a small confusion made my new life challenging. I have been enjoying it a lot, but I've realized that I have less chance to output implement what I experienced and what I thought during my those days, and I feel less confident to communicate communicating with people. Therefore, I decided to start writing notebooks here to practice my English. I would be happy if you correct my English or comment on it.
I used to work in Japan for about five years, and now I don't because of my English conversation skills. This year, I am going to be active to output, improve my English skills, be fluent in speaking English, and get a job. This is my new year's resolution.
