Yo también intento ser realista, porque esa actitud me ayuda a no desanimarme.

Yes. Yo is optional in Spanish because the verb form intento already tells you the subject is I.

So both of these are possible:

• Yo también intento ser realista...
• También intento ser realista...

Including yo can add a little emphasis or contrast, for example if the speaker means I too, not just someone else. In many cases, Spanish leaves subject pronouns out unless they are needed for emphasis, contrast, or clarity.

También means also or too.

In Yo también intento ser realista, it means I also try to be realistic or I too try to be realistic.

Its position is very natural here:

• Yo también intento... = I also try...

Spanish often places también before the verb or after the subject. The exact position can shift slightly depending on what is being emphasized, but this version is very standard and natural.

Because realista describes a general way of being, not a temporary state.

Spanish usually uses:

• ser for identity, characteristics, and general traits
• estar for temporary states, conditions, or locations

So:

• ser realista = to be realistic, to have a realistic outlook

Using estar realista would sound unusual here, because the sentence is talking about a general attitude or habit, not a temporary mood.

Some Spanish adjectives change form depending on gender, but others do not.

For example:

• realista stays the same:
  • soy realista
  • ella es realista

This adjective ends in -ista, and many -ista words keep the same form for masculine and feminine.

Examples:

• un artista / una artista
• un idealista / una idealista
• un realista / una realista

Because porque is the conjunction meaning because.

Spanish distinguishes several similar-looking forms:

• porque = because
• por qué = why
• el porqué = the reason
• por que = a less common combination in other structures

In your sentence:

• ..., porque esa actitud me ayuda...
• ..., because that attitude helps me...

So porque is the correct form.

Esa actitud means that attitude.

Spanish demonstratives often work like this:

• esta = this
• esa = that
• aquella = that over there / that one farther away

Here, esa actitud refers back to the attitude just mentioned: being realistic. In English we often also use that in this kind of situation:

• That attitude helps me...

So esa is very natural because the speaker is referring back to an idea already mentioned.

Me means me and functions as an indirect object pronoun here.

• esa actitud me ayuda = that attitude helps me

Literally, the attitude is helping me do something.

Spanish often uses object pronouns before the conjugated verb:

• me ayuda = helps me
• te ayuda = helps you
• nos ayuda = helps us

After ayudar, Spanish often uses this pattern:

• ayudar a + infinitive

So:

• me ayuda a no desanimarme
• it helps me not get discouraged

The a belongs to the structure of the verb:

• ayudar a hacer algo = to help someone do something

Examples:

• Me ayuda a estudiar. = It helps me study.
• Nos ayuda a entender. = It helps us understand.

So the a is required by the verb pattern.

Because the speaker is saying not to get discouraged.

In Spanish, when you negate an infinitive, no goes directly before it:

• no desanimarme = not to get discouraged
• no olvidar = not to forget
• no rendirse = not to give up

So:

• me ayuda a no desanimarme
• it helps me not get discouraged

They both refer to me, but they belong to different verbs.

1. me ayuda
   Here, me goes with ayuda:

   • that attitude helps me

2. desanimarme
   Here, -me goes with desanimar:

   • to discourage myself / to become discouraged

So they are not duplicates by mistake. Each one is attached to a different part of the sentence.

A useful way to see it is:

• esa actitud helps me
• not to get myself discouraged / become discouraged

Yes, desanimarme is the infinitive desanimarse with me attached.

• desanimar = to discourage someone
• desanimarse = to get discouraged, to lose heart

So:

• no desanimarme = not to get discouraged

In English, we usually do not say discourage myself in this context. We say get discouraged. Spanish often uses the reflexive form where English uses a non-reflexive expression.

Examples:

• No quiero desanimarme. = I do not want to get discouraged.
• Se desanima fácilmente. = He/She gets discouraged easily.

Not in this structure.

With ayudar, the normal pattern is:

• ayudar a + infinitive

So:

• me ayuda a no desanimarme = correct

Using para would change the structure and would not fit naturally after ayuda in this sentence.

Compare:

• Esa actitud me ayuda a no desanimarme. = That attitude helps me not get discouraged.
• Tengo una actitud realista para no desanimarme. = I have a realistic attitude so that I do not get discouraged.

So para can express purpose, but after ayudar, a + infinitive is the standard choice.

Because the sentence is saying that attitude, and esa already determines the noun.

In Spanish, demonstratives like este, ese, aquella normally replace the need for an article:

• esa actitud = that attitude
• not la esa actitud

Just like in English, you say that attitude, not the that attitude.

No. With an infinitive, object or reflexive pronouns are normally attached to the end.

So:

• desanimarme = correct
• me desanimar = incorrect

Spanish allows pronouns to attach to:

• infinitives: desanimarme
• gerunds: desanimándome
• affirmative commands: desanímate

But with a conjugated verb, the pronoun usually goes before it:

• me desanimo
• me ayuda

Yes, it sounds natural and idiomatic in Spain.

The sentence is clear, standard, and very normal:

• Yo también intento ser realista, porque esa actitud me ayuda a no desanimarme.

A native speaker might also say small variations such as:

• Yo también trato de ser realista...
• ...porque esa forma de pensar me ayuda a no desanimarme.
• ...porque así no me desanimo tanto.

But your original sentence is absolutely natural and correct.
