Why "where" is necessary in here? Can I skip it?

Is it okay to use 2 adverbs in a row?

Yes, it is grammatically correct to have two adverbs in a row in a sentence. Let me show examples to elaborate the point. "I am quite well." In this sentence, there are two adverbs in a row, 'quite' and 'well.' ‘Well’ is modifying the verb be (am) and ‘quite’ is modifying the other adverb ‘well.' "He did extremely well." In this sentence, there are two adverbs 'extremely' and 'well' in a row. ‘Well’ is modifying the verb do (did) and ‘extremely’ is modifying the adverb ‘well.’

What does "be over something" mean?

To be over something/someone means to no longer care or have strong feelings towards something. It means that a situation or person no longer affects you the way it used to. This is the meaning intended by the speaker in this video. Ex: A: How are you doing? You broke up recently. B: Totally fine. I'm over it. Ex: I was really upset about failing the interview but I'm over it now.

As a suffix, what does "-pokes" mean? Could you give me some examples?

Actually, "pokes" is not a common suffix! It's only used with the word "slowpoke," which is an informal word for someone who moves or acts slow; a very slow person. The word "poke" itself means a push or thrust with something long or pointed, like a finger. There was something called a "poke" to keep sheep and animals form jumping farm fences, it slows them down. Which is where the term "slowpoke" came from. Ex: Please stop poking my shoulder, John. It's annoying. What do you want? Ex: The slowpokes were catching up with us in the race.

Would it sound weird if I say "having something to say and saying it to be listened to" here instead of "Having something to say... and the way to say it so people listen to it"?

Good question! No, it wouldn't sound weird to say "having something to say and saying it to be listened to" here. This sentence sounds perfectly fine and is okay to use. It still indicates a purpose of getting people to listen, however, it doesn't quite express that there is a struggle of people listening in the first place like the original sentence. If you wanted to express this more clearly, you could also rephrase the sentence as "having something to say and saying it in a way people will listen to".

What's the main difference between an "enemy," a "competitor," a "rival," and an "opponent?"

All of the words describe someone who is competing against someone else, but there are largely not interchangeable because each has a different context. "Enemy" means someone who is actively opposed to or hostile to someone or something. Ex: Germany and France were enemies in the Second World War. "Competitor" means someone who takes part in an organized competition; a person or group attempting to achieve the same goal as another. Ex: Every country sends competitors to the Olympic Games, but only some win medals. Ex: Our company's primary competitor has lower prices but lower quality products than us. "Rival" means a person or organization that is competing closely with another in an aggressive way and for the same goal. It's similar to competitor but stronger and more intense as an expression. It can also be used as a verb to say that someone or something is potentially equal to another in terms of performance. Ex: Two boys like the same girl, and both are trying to impress her. They are rivals for her love. Ex: There are no runners who can be rivals to Usain Bolt. Ex: Tigers rival lions as the most dangerous big cat. => used as a verb Opponent means someone who competes with or opposes another in a contest, game, or argument; usually no emotional aspect. Ex: The chess master struggled against his opponent but eventually won the game. Ex: We don't need to see our coworkers as opponents when trying to get a promotion.
