The clip we studied was from this video:    • 【不動産Gメン滝島が斬る】自宅購入間際のEXIT・りんたろー。に警鐘「バブ...

The Japanese lines we studied:
「不動産を制する者は人生を制する」になります。
(「ふどうさん を せいする もの は じんせい を せいする」になります)
The master of real estate is the master of his own life. That is our goal.

ウォー！ウォー！
Whoa! Whoa!

はい。
Yes.

そこまで言い切る！
(そこまで いいきる！)
You really think it’s that important?

言い切ります。
(いいきります。)
I do.

ちょっと人生制したいっすわー。 ← Didn't elongate that final わ in the video, but I probably should have.
(ちょっと じんせい せいしたい っす わー。)
I want to be the master of my life.

制したいですね。
(せいしたい です ね。)
Me too.

We also saw:

世界を制した男
(せかい を せいした おとこ)
the man who dominated the world (e.g. in a sport)

世界を支配する
(せかい を しはい する)
to rule the world

The lessons from NativShark (https://nativshark.com/) that appeared in the video:
- Doing something "completely" with Vきる
(https://app.nativshark.com/lessons/kiru)
- How to talk like an お嬢様
(https://app.nativshark.com/lessons/on...)

↑ You need a free account to be able to read those lessons. For those studying with NativShark, please don't be intimidated if the language in those lessons seems difficult. Since our study path teaches one concept at a time, you would be ready for those lessons when you reached them. ^_^
