Αν διαβάζω λίγο κάθε μέρα, πετυχαίνω πιο συχνά τον στόχο μου και νιώθω καλύτερα.

Because Greek usually does not need subject pronouns when the verb ending already shows who is doing the action.

• διαβάζω = I read / I am reading
• πετυχαίνω = I achieve / I succeed
• νιώθω = I feel

So the I is built into the verb form.

You could add εγώ for emphasis, but it is not necessary:

• Αν εγώ διαβάζω λίγο κάθε μέρα... = If I read a little every day...

That sounds more emphatic, like if I am the one who reads...

Because this sentence describes a general habit or repeated pattern:

• Αν διαβάζω λίγο κάθε μέρα... = If I read a little every day...
• πετυχαίνω... και νιώθω... = I achieve... and feel...

In Greek, the present tense is very natural for things that happen regularly, typically, or whenever the condition is true.

So this is not about one single future event. It is about a repeated cause-and-effect relationship.

αν means if.

In this sentence, it introduces a condition:

• Αν διαβάζω λίγο κάθε μέρα = If I read a little every day

Because the sentence talks about a repeated situation, αν here can also feel close to whenever in English:

• Whenever I read a little every day, I achieve my goal more often and feel better

So αν is the word that sets up the condition for the rest of the sentence.

This is a very common question.

• διαβάζω = present, habitual, ongoing
• διαβάσω = aorist subjunctive form, often used for a more specific or future event after αν

In your sentence, διαβάζω is used because the meaning is habitual:

• If I read a little every day, I more often achieve my goal...

If you used διαβάσω, the sentence would sound more like a specific future condition. For example:

• Αν διαβάσω λίγο σήμερα, θα νιώσω καλύτερα.
• If I read a little today, I will feel better.

So:

• αν + present → repeated/general situation
• αν + aorist subjunctive form → one event or a more definite future condition

It can mean both, depending on context.

Common meanings of διαβάζω:

• to read
• to study

In a sentence like this, especially with κάθε μέρα, many learners would understand it as either:

• I read a little every day
• I study a little every day

Both are possible. Greek often uses διαβάζω where English might prefer study, especially in school or learning contexts.

Here λίγο means a little and functions like an adverb modifying διαβάζω.

So:

• διαβάζω λίγο = I read a little / I study a little

It does not have to agree with a noun here, because it is not directly describing a noun. It is describing the amount of the action.

Compare:

• διαβάζω λίγο = I read a little
• λίγο νερό = a little water

So in your sentence, λίγο is the natural form.

κάθε μέρα means every day.

It is written as two words because:

• κάθε = every
• μέρα = day

So literally it is every day.

This is different from English, where learners often confuse:

• every day = each day
• everyday = ordinary, usual

In Greek, κάθε μέρα is simply the normal expression for every day.

A one-word alternative with a similar meaning is:

• καθημερινά = daily / every day

Here πετυχαίνω means achieve, reach, or meet successfully.

With στόχο, it commonly means:

• πετυχαίνω τον στόχο μου = I achieve my goal

But πετυχαίνω can have other meanings in other contexts, for example:

• I hit
• I succeed in
• I happen to meet

So the exact meaning depends on the object or context.

In this sentence, with τον στόχο μου, the meaning is clearly achieve my goal.

Because τον στόχο μου is the direct object of πετυχαίνω, so it must be in the accusative case.

• nominative: ο στόχος μου = my goal
• accusative: τον στόχο μου = my goal, as the thing being achieved

Since πετυχαίνω takes an object, Greek uses the accusative:

• Πετυχαίνω τον στόχο μου.
• I achieve my goal.

That is why you see:

• τον instead of ο
• στόχο instead of στόχος

Because Greek unstressed possessive forms like μου, σου, του, της usually come after the noun.

So:

• ο στόχος μου = my goal
• το βιβλίο μου = my book
• η φίλη μου = my friend

This is the normal Greek pattern.

English puts the possessive before the noun:

• my goal

Greek usually puts it after:

• ο στόχος μου

So τον στόχο μου is exactly what you would expect in normal Greek.

πιο συχνά means more often.

It is formed with:

• συχνά = often
• πιο συχνά = more often

So πιο is used to make a comparative.

Examples:

• συχνά = often
• πιο συχνά = more often

This is very common in Greek:

• γρήγορα = quickly
• πιο γρήγορα = more quickly

In your sentence, πιο συχνά tells you that the speaker achieves the goal more frequently.

Because καλύτερα here means better in the sense of feeling better, not being a good person.

This is a very common Greek pattern:

• νιώθω καλά = I feel well
• νιώθω καλύτερα = I feel better

So καλύτερα is the natural form after verbs like:

• νιώθω = feel
• είμαι = be
• πάω in some expressions about how things are going

If you said:

• νιώθω καλός
  or
• νιώθω καλή

that would sound more like I feel like I am good / I feel morally good / I feel like a good person, which is not the same idea.

So for physical or emotional well-being, καλύτερα is the normal choice.

Yes, it is normal and correct.

The first part of the sentence is a conditional clause:

• Αν διαβάζω λίγο κάθε μέρα,

Then the main clause follows:

• πετυχαίνω πιο συχνά τον στόχο μου και νιώθω καλύτερα.

Greek usually separates this kind of introductory if-clause with a comma, just as English often does.

So the comma helps show the structure clearly:

• condition first
• result after

Because the speaker is saying that the condition leads to two results:

1. πετυχαίνω πιο συχνά τον στόχο μου = I achieve my goal more often
2. νιώθω καλύτερα = I feel better

The conjunction και means and, so it links the two result verbs.

This is a very normal Greek structure:

• Αν..., κάνω Χ και νιώθω Ψ.
• If..., I do X and feel Y.

Both verbs share the same subject, which is still I.

Yes, to some extent. Greek word order is more flexible than English because the verb endings and case endings give a lot of grammatical information.

The original sentence is very natural:

• Αν διαβάζω λίγο κάθε μέρα, πετυχαίνω πιο συχνά τον στόχο μου και νιώθω καλύτερα.

You could move some parts for emphasis, for example:

• Αν κάθε μέρα διαβάζω λίγο, πετυχαίνω πιο συχνά τον στόχο μου...
• Τον στόχο μου τον πετυχαίνω πιο συχνά, αν διαβάζω λίγο κάθε μέρα...

But the original is probably the best version for a learner because it is:

• clear
• neutral
• natural

So yes, Greek word order can move around, but not every order is equally natural.
