40 mins is a lot of time! I think you can keep it up! :)

Thank you, I hope so!

加油！Not sure if it helps, but I break it up into chunks. I find it hard to have a review session longer than 25mins. I do the 'easy' (imo) type of cards first - only pronunciation&tones and definitions. Once I've done those, I do writing cards.

I second what Megan said, breaking your study session into shorter periods is way more manageable, and it’s also easier to find the time :)

What also helps me is I use skritter only for writing, but disable definitions, tones, and such, since I get that through Pleco or Anki, so reviewing in skritter is a little redundant. Also, if you mimic a lot you don’t have to really worry about reviewing tones as much I found. But see what works best for you :).

Thanks to everyone for all of the advice! :)

Ouh! Interesting conversation! I wanted to chime in because it's all the contrary for me and I thought maybe a different perspective would be welcomed! I find it hard to have a short study session because I found that for me if I interact more with the words or characters to learn I understand and memorize them better. The shorter it is, the more my brain seems to think that it's not important, haha! Therefore, during vocab study sessions, I usually end up reviewing radicals/similar looking characters/words that I confuse and try to understand why I make that mistake, I also like to take the time to find words that are more relevant to my life that includes characters I need to know for a chapter. For example, I kept forgetting this 溫泉, I looked into individual meanings then realized that "溫" is used for 溫暖 (warm) /溫柔 (gentle) and I hear these words often in tv shows so it's easy to be exposed to them too and not forget it! So now, I remember 溫! Now, I didn't know "泉" but I realized that its meaning is spring and it is used in spring water "潛水“ for bottled water (!), which is now very useful to know! So through finding 潛水 more meaningful, I remember the 潛 in 溫泉 better. I hope my explanation of my approach to vocab makes sense!
