Como sigas siendo tan terco, vas a discutir con todo el mundo y no vas a escuchar a nadie.

At the start of a sentence, como + subjunctive can introduce a warning or threat, and it means if.

So:

• Como sigas... = If you keep on...
• but with a stronger tone than plain si

It often suggests something like if you go on like that, there will be consequences.

Because after sentence-initial como in this warning structure, Spanish uses the present subjunctive.

So:

• Como sigas... = correct
• Como sigues... = not correct in this meaning

The subjunctive is used because the speaker is referring to a possible future situation and expressing attitude toward it, not just stating a fact.

Seguir siendo means to continue being or to keep being.

So:

• sigas siendo tan terco = you keep being so stubborn

This is a very common structure:

• seguir + gerund = keep doing something
• seguir siendo = continue to be

With ser, Spanish often uses seguir siendo rather than trying to force a gerund structure.

Tan means so, while muy means very.

Here, tan fits better because the sentence is about a cause leading to consequences:

• tan terco = so stubborn
• muy terco = very stubborn

You could say muy terco, but tan terco sounds more natural when the idea is you’re so stubborn that this is what will happen.

The adjective has to agree with the person being addressed.

• terco = masculine singular
• terca = feminine singular

So this sentence is being said to a male tú. If speaking to a woman, it would be:

Como sigas siendo tan terca, vas a discutir con todo el mundo y no vas a escuchar a nadie.

Spanish often leaves out subject pronouns because the verb form already shows who the subject is.

Here:

• sigas = you continue
• vas = you are going to

So tú is understood without needing to say it. You could add tú for emphasis, but normally it is omitted.

Ir a + infinitive is a very common way to talk about the future in everyday Spanish.

So:

• vas a discutir = you’re going to argue
• no vas a escuchar = you’re not going to listen

Spanish could also use the simple future:

• discutirás
• no escucharás

But vas a... sounds more conversational and often feels more immediate or predictable.

Yes, grammatically you could reduce repetition in some contexts, but repeating vas a here sounds natural and clear, especially because the second clause is negative:

• vas a discutir... y no vas a escuchar...

Repeating it helps separate the two consequences and gives the sentence more rhythm and emphasis.

In this sentence, discutir means to argue.

That’s clear because of the context:

• discutir con todo el mundo = argue with everyone

Spanish discutir can sometimes mean discuss/debate, depending on context, but when you see discutir con alguien, it often means to have an argument with someone.

Literally, yes, but idiomatically todo el mundo means everyone or everybody.

So:

• con todo el mundo = with everyone

Even though it refers to many people, it is usually treated as grammatically singular:

• Todo el mundo sabe eso = Everybody knows that

There are two things happening here.

1. Personal a
Because nadie refers to people, Spanish uses the personal a when it is the direct object:

• escuchar a alguien
• escuchar a nadie

2. Negative structure
After no, Spanish keeps the negative word:

• no vas a escuchar a nadie = you’re not going to listen to anyone

This is normal Spanish, not a mistake or a double negative in the English sense.

Yes. That would also be correct.

• Si sigues siendo tan terco... = neutral if
• Como sigas siendo tan terco... = stronger, more like a warning

So both are possible, but como + subjunctive sounds more forceful and emotional. Also, this como structure normally appears at the beginning of the sentence.

It sounds like a warning, criticism, or reproach.

The speaker is basically saying that if the other person keeps acting stubbornly, the likely result will be:

• arguing with everyone
• listening to nobody

So it is not neutral or purely descriptive. It has a clearly judgmental, cautioning tone.
