That is correct.

You can say 「イギリスからきました」 only when you are NOT in England.

Hence this person said :
「～きました」と書くと、今は日本に住んでいるみたい なカンジになっちゃう
which means:
"If you write 「来ました」, it sounds like you are now in Japan or something."

Ah I see, awesome! Thank you ^_^

S/He is saying:

"If you said 「大阪と東京はとても凄いですよ！」, one would get the impression that you are talking to someone who has never been to Osaka or Tokyo about how freakin' awesome those cities are.

"If you said 「大阪と東京はとても凄いですね！」, one would get the impression that you are talking to someone who has either been to or lived in either Osaka or Tokyo about how friggin' exciting you thought those cities were when you visited them.

"In this case, most of your readers would be Japanese: therefore, I thought it would be better for you to use 「ね！」 as the sentence-ender."

Now in my own words.
「よ」 when it is new information for the addressee.
「ね」 when it is new information for the speaker. Kind of seeking agreement.

Admittedly, what I just said above I said with an amount of over-simplification. However, this is generally true and it is something very few Japanese-learners appear to understand.

Ahhhhh. Makes so much sense! I have had a look at it before, but I everything I read about it was a bit sketchy and over complicated.

My text book said 「よ」 is for making a statement and 「ね」 is for seeking agreement, so as a result I was confused about how/when to use 「よ」 specifically and didn't really bother. I thought I'd try it in this case to get some clarification if it was wrong, so that's cool.

Thank you so much! *_*

Thanks for an awesome and REALLY helpful answer! seeing as the chapter is about taking action and also considering the author's way of thinking your suggestion no.2 'do it anyway' definitely makes the most sense.

also i'd just like to double check if ーてしまえ　is the command form of －てしまう? so basically the author is strongly urging the reader to take a chance i guess..

actually the full sentence was 合言葉はいつも、やるだけやっちまえ but i guess doesn't make much difference.

Yes, it is a non-polite, colloquial command form.

Hi, I would like to know which of the following sentences is the correct one?

予定の五時間遅れで到着する。

予定の五時間遅れて到着する。

The first one.

To make the second one correct with 「て」, you need to change the 「の」 to 「を」 or 「より」.

comfort
 

Hi! this time what keeps bugging me is that I'm unsure of how to say 'you need comfort' or 'looks like you need comfort' in a natural way. When I try to bend my grammar I get something like 慰めるのはいるらしい　or 癒やされることがいりそう but i've never heard it said so can't tell if either of them sound natural.

any input would be highly appreciated :vsign:

Neither of those is grammatical nor natural. One cannot say either 「のはいる」 or 「ことがいる」.

I would phrase it as:
「癒しを必要としているようです。」
「癒しを求めているようだ。」
, etc
