Self-Comment
• UI Part is always so hard to push through. Easily distracted😂
• When I run android emulator, speaker seems to be affected..? WT..Interesting and annoying. Curious what’s happening..
• Tomorrow I have to checkout in morning, move to another guesthouse. Then my friends come over at evening. So I’ll have to spend three hour gap efficiently and productively. (Actually I like this kind of tight schedule, it somehow feels like a game mission) + I might use pass at Sunday.
Goals Tomorrow
• Halfway through Lesson6
