Hey! Thanks for your content, I found it by chance but absolutely don't regret reading it. I'm still in college so I don't have time to learn new languages but it's definitely on top of my to-do list, and based on personal experience your advice feels trustworthy.
After my second year of middle school I started to really enjoy learning English so as I already watched lots of videos I started to watch some in English, and by my first year of high school I'd begin to speak English quite fluently, even though I wasn't aiming for this at all. And yes, enjoying yourself makes learning way more efficient.
As for Google translate, I genuinely agree that it has improved a lot over the last years. I'd say it used to be very literal, at least It felt like it. I'm French and I hear a lot that French grammar is a bit hard to master compared to other languages though as a native speaker it's difficult to judge. The point is, when I translated something, let's say 7/8 years ago, sure I sometimes could make out the meaning of the sentence I translated but most of the time it made no sense. Nowadays you'll almost always get a good French translation, and apparently it's not an easy language so yeah, massive improvement.
