Based on a conversation with one of my Japanese friends. She says that English has a lot more ways to encourage people. (Great! Good job! Amazing! Excellent! Fantastic! Wonderful! etc.) However, she feels like there are only a few words that can be used to encourage each other in Japanese. (すごい！　上手！　すばらしい！　出来たね！) Since she has four small kids, I'd like to learn as much ふわっと日本語 as possible!

Maybe also how to say you're proud for someone and how much weight that kind of thing carries in Japanese.
