It would be great if Portuguese people spoke as clearly as in these videos sometimes, even though it’s a bit “too much”. 
@Paul - No worries, you found out what you don’t like etc. We’re always still figuring ourselves out. It was a great read anyhow. I’d be interested in whatever challenges or missions you put up.
I totally get the “novelty” part - this is the main reason my whole life I was never interested in European languages (with Latin script). They feel “boring”! I grew up watching boring black and white movies about Brits and Americans speaking French and Italian in Paris and Rome…and harsh British schoolmasters hammering Latin into their students…
Back in Year 9 when I was 14, we had to choose between Japanese and Latin. I thought to myself, “Latin is ‘dead’, but Japanese is ‘Oriental’.” I also chose music instead of French. I hated my French teacher - she spoke like she had dressmaking pins clenched between her teeth…so I took up flute and violin from scratch (which I loved).
Studying interesting languages with different scripts and challenges, like Japanese, Mandarin, Russian, Persian, (& potentially Hindi/Urdu, Egyptian Arabic) seem way more fun. It’s also kinda like when we were kids, pretending to be spies and cracking secret codes…
I click with “Asians” more than Europeans, too - no idea why.
Have fun.
‘Instead of’ is completely normal English, at least I think it is.
When I learned Spanish around three years ago, I had moments where the language started to look like a silly parody of English, only with -o and -a atached to the ends of words. - YouTube 
And of course knowledge of any other form of latin has a similar effect. Large parts of it were so easy, I felt like learning something like Dutch for a German speaker. Since I also need a bit of a lingonerd stimulation I thought about adding languages on the side a few times. What kept me going was the reality of the Spanish world. Looking forward to Spain and Latinoamerica, listening to the music, anticipating food and brunettes, imagery, literature. If you study it in a more academic distanced style, exemplified by the video ‘a polyglot’s daily linguistic workout’ then Spanish is probably not the most taxing brain-wrencher out there. Still I enjoyed the reading and show-watching. But maybe it was just my strong personal brunette factor overriding the diminishing factors ;pp
“But maybe it was just my strong personal brunette factor overriding the diminishing factors”
And now your most active languages are Chinese, Japanese and Russian…
Encouraged :)!
The “4 books about four different topics in French in six weeks” mission would be a perfect idea for total immersion!
