No me gusta comparar mi progreso con el de otras personas.

Because gustar works differently from to like in English.

In Spanish, gustar literally works more like to be pleasing to. So:

• Me gusta comparar... = Comparing... is pleasing to me
• Natural English translation: I like comparing...

Here:

• me = to me
• gusta = is pleasing

So No me gusta comparar mi progreso... means I don’t like comparing my progress...

Using yo gusto would mean something like I am pleasing / I am liked, which is a completely different idea.

Because the thing being liked is the whole action comparar mi progreso con el de otras personas.

An infinitive verb phrase like comparar... counts as a singular idea in Spanish, so you use gusta.

Compare:

• Me gusta leer. = I like reading.
• Me gusta viajar. = I like travelling.
• Me gustan los libros. = I like books.

So:

• If what follows is an action in the infinitive, use gusta
• If what follows is a plural noun, use gustan

Me is the indirect object pronoun meaning to me.

In sentences with gustar, Spanish marks the person who feels the reaction with an indirect object pronoun:

• me = to me
• te = to you
• le = to him/her/you formal
• nos = to us
• os = to you all
• les = to them/you all

So:

• No me gusta... = It is not pleasing to me
• Natural English: I don’t like...

Because in Spanish, standard negation usually puts no directly before the verb.

Here the verb phrase is me gusta, so:

• Me gusta comparar... = I like comparing...
• No me gusta comparar... = I don’t like comparing...

This is the normal pattern:

• No quiero ir. = I don’t want to go.
• No me interesa. = It doesn’t interest me.
• No me gusta. = I don’t like it.

Because after gustar, Spanish often uses an infinitive to talk about liking an action.

So:

• Me gusta cocinar. = I like cooking.
• Me gusta estudiar español. = I like studying Spanish.
• No me gusta comparar mi progreso... = I don’t like comparing my progress...

This is very common in Spanish. The infinitive often does the job that English sometimes does with -ing forms.

Because the most natural way to say my progress in Spanish is with a possessive adjective before the noun:

• mi progreso = my progress

Spanish can sometimes use forms like el mío / la mía / los míos / las mías, but those are usually used differently, often when the noun is omitted or when you want contrast:

• Mi progreso es lento, pero el tuyo es constante.
• Este es mi libro; el tuyo está allí.

So in this sentence, mi progreso is the normal and natural choice.

El de otras personas means the one of other people or more naturally that of other people / other people’s.

It avoids repeating progreso:

• mi progreso = my progress
• el de otras personas = the progress of other people

You could expand it fully as:

• No me gusta comparar mi progreso con el progreso de otras personas.

But Spanish often avoids repeating the noun when it is already clear. So el de otras personas is a very natural shortened version.

Because el stands in for the omitted noun progreso.

Think of it like this:

• mi progreso = my progress
• el de otras personas = the one of other people

Here, el is not really being translated as the in the normal way. It is more like a placeholder meaning the one / that.

A useful parallel:

• Mi coche es más rápido que el de mi hermano. = My car is faster than my brother’s.

There too, el de mi hermano means my brother’s car.

Spanish often uses personas to make the meaning explicit: other people.

• otras personas = other people

You could sometimes hear los demás depending on context, but it is not exactly the same in tone.

Compare:

• otras personas = other people
• los demás = the others / everyone else

In this sentence, otras personas is clear, neutral, and very natural.

Because comparar is commonly used with con when you compare one thing with another:

• comparar A con B = to compare A with B

So:

• comparar mi progreso con el de otras personas = to compare my progress with that of other people

You may also see comparar A y B in some contexts, especially when simply setting two things side by side, but comparar ... con ... is very standard and very common.

Yes, but it means something slightly different.

• No me gusta comparar mi progreso con el de otras personas. = I don’t like comparing my progress with other people’s progress.

• No me gusta compararme con otras personas. = I don’t like comparing myself with other people.

The second version uses compararme because the action is reflexive in the sense of comparing myself.

So both are correct, but the focus changes:

• comparar mi progreso... focuses on progress
• compararme... focuses on yourself as a person

Yes, absolutely.

These two mean the same thing:

• No me gusta comparar mi progreso con el de otras personas.
• No me gusta comparar mi progreso con el progreso de otras personas.

The version with el de is usually preferred because it sounds less repetitive. Spanish often avoids repeating a noun that has just appeared.

So:

• el progreso de otras personas = fully stated
• el de otras personas = shorter, more natural in many cases

This is the most neutral and natural order.

• No me gusta comparar mi progreso con el de otras personas.

Spanish word order is somewhat flexible, but this version is the standard way to say it. You could rearrange it for emphasis, but it would sound less neutral, for example:

• Comparar mi progreso con el de otras personas no me gusta.

That is grammatically possible, but it sounds more marked or emphatic. For normal conversation, the original sentence is the best choice.
