I have this written down on my white board for some time now. It's a reminder for me to study Korean and keep progressing. I have some ideas and goals for July, and it included study Korean every day.
Unfortunately, I haven't made that happen. Life happens, and also getting sick makes it hard to stay up with these plans. I know that putting too much pressure and time doesn't work for me. Thats why I wrote for 30 mins. I think if its more than that then you can start to lose focus and get brain tired.
I also enjoy more so studying in the later part of the day, in the evening. That's my favorite part of the day and usually feel that I have more focus and energy. It's a time of day I look forward to as well.
I will attempt to keep updated in my Korean language learning journey!
