Sorry to hear, energy levels are still hard to get right despite maturing/aging, it's one of those things you can't really ever get right 100% of the time, even up till your 70s. Hope you feel well enough to start again soon.
A good teacher can make a huge difference in your life. I had okay teachers but none of them made me go mad for learning like I am now for languages and such. I think some random person on IRC did that and I don't even know their name anymore.
You get that study high after a good day, it's very worthwhile just for that, lol.
Grammar is always a pain point. Been doing Japanese for a few years now, but I always mix up things like no, ni and he (not all with each other), nvm ha and ga.
Late to this weeks entry, but my study is going okay. Few days full hour each, few days just doing 5 mins. Been more on the 30 minute mark though. Maths suffered greatly, and this week has just been hectic and had really bad news a while back, so not in the greatest of spirits. Still, managing to do a bit in each day. I actually put off new lessons for my Japanese and just did reviews the whole time, some days the pile still surpasses 100 despite giving it my all each day. I guess it's just like that at times.
Doing new lessons for Spanish using Migaku, new app to me, but most of those words I already knew, or could tell due to similar sounds to English. Elephant and Giraffe and others are all very similar. My GF's native language is Spanish, so sometimes she ends up saying words like these but in Spanish, so I know what she's saying, and I now totally understand the confusion. There's a lot of words out there that need more attention than just knowing what it looks like but being able to pronounce them. It'll be many years before I can manage my Spanish as well as she manages her English. Also, she's keen on picking up Japanese too, so we might both go a combined Duolingo/MaruMori/Busuu route, along with other resources.
Now if I could also just convince her to join me in my future Lojban and Irish studies...
