The one about not saying "I think maybe" is one I actively try to do. Assertiveness is something that doesn't come naturally to me but I've been in too many situations where my lack of assertiveness comes across as uncertainty and introduces confusion into discussions where actually I do know what I'm talking about.

Jack Whitehall telling a variation of this joke on Graham Norton: https://youtu.be/UIL9CiUDHp0

Using Lens and Google translate gave me this:

I live beautifully here.
The working environment can't live, and the welfare is gone.
But don't worry, only about ten people are seriously injured every day,
And I am also very careful. We opened a small shop, and the business is doing well.
Although I don't know English very well, I can speak a little
Right. Understand what those white people are saying.
I hope I can get ahead! I will work hard here, and
Be careful with your body.
How are you? I miss you very much and hope we can meet again.
