I'm really bad with titles part I

Hi. I will admit (that) I don't really know how to start this entry right now. I've been staring at my screen with a blank mind without writing a word for a while, trying to find the perfect sentences despite knowing perfectly well that I won't. Because, well, that's just the way I am.

The latest (I think this works, but "last" or "past" might sound better.) year has been quite harrowing for me. I don't know how much I'm allowed to write about it here, and I don't know if I really want to do it, either. I feel like I have a lot to vent out and yet, I can't think of anything new. I'm wondering why, exactly, did I choose this subject. Parts of me want/Part of me wants to start over and write about petty things instead, like the last meal I ate or the last time I had fun. But this is it, I think I just can't write anything significant about it.

I ate ramen when I woke up this afternoon. It tasted like ramen. Duh.
I have trouble remembering the last time I had real, quality fun. Laughing to silly videos to distract my mind is as far as it goes, I think.

'' Write about learning a language ''.

Yeah, that might be a good idea.
Why do I want to perfect my English?

Well first of all English is pretty much the language of the internet, which is why I managed to understand it well in the first place. I had courses as a kid, but it didn't interest me back then. I always hated learning in a school environment. So ("Thus" is correct, but a bit too formal.) I never really learnt from there. It didn't bring me far in life however. Anyway. Back to the topic.

1. Both are fine. *northernmost though 2. Yes, although the word "sit" is still in the present (which sounds fine to me anyway). I think a more natural way to say that sentence would be "Was it really necessary for me to sit there watching you the entire time you were rehearsing for the play?" 3. To me, "rankings" refers to a list, whereas "ranking" would refer to an individual place on the list, however it's a bit flexible, and "ranking" could probably be used to refer to the whole list, but it wouldn't sound as good. e.g. "US News > World Report released its annual college rankings Tuesday," but "Harvard's ranking was in the top 10".

These two pie charts illustrate respectively the Australian household energy use and the Australian household greenhouse gas emissions.
In both charts, water heating makes up about 30% of the total. It's slightly above 30% for the gas emissions. The same phenomenon shows up for the cooling percentage which represents 2% of both graphs.
Turning now to the differences, the lighting and the refregiration portions are 2 times larger comparing the second chart to the first one. Similarly, the other appliances drop to almost half/rise to almost double too. It differs for the heating rate which decreased significantly from 42% to 15%, according to the study.
To sum up, despite the fact that heating represents almost half of the energy use in Australian households, it's lighting, refrigeration and the other appliances which emit the most gas into the atmosphere.

Very well written.

This Year.

Time flies by. This month is already the last month of the year.
This year is a milestone of my life, because I moved out of Berlin in April, and into the U.K for six months until the middle of October. Afterwards, I travelled to Iceland, Italy, Berlin again and finally Morocco now.
Back to the time when I lived in Berlin, what I mainly did was working at a restaurant a lot and drinking beer or shots every night. Meanwhile, I studied academic English for IELTS very hard as an online course every day. In fact, the time spent was not bad, because the study was valuable and a lot of worthy vocabulary still remains in my English.
Otherwise, I have truly learned and experienced a ton of new things this year, especially since leaving Berlin. I have fortunately met new people from a bunch of places around the world. The more I speak with them in English, the more my English gets better. In addition, I have got confidence in myself from new experiences. I was not confident about myself at all.
I, now, study Spanish and English. (You only need one of these commas. Either one is fine, but not both.) Furthermore, I am trying to improve drawing and playing the harmonica. I have really enjoyed my life in Morocco in/throughout/during these days.

Are there any mistakes?

I just watched a documentary about a French politician. I found this documentary on the internet.
The documentary was more about the life of this young politician than his political ideas.

It depends on the person, but I find that kind of documentary interesting. (I wasn't really sure what you were trying to say with this sentence, but I did my best to change it into what I thought was right.)
Basically I like stories about people's lives, even though it's a quick summary of someone's journey.

Another reason that I have to agree with the statement, is that the people who live happiest and with the least stress, very often are more efficient in their jobs, or anything that they do, because they enjoy it when doing it, as result their work will be as good as possible and we have a better person around us.
Finally, I would say that almost all of us, at some point in our life, we think of how life would be if we were to do things that are enjoyable for us? A life without stress, in a job or career that we want? And if this were possible would you like to follow it?
