I'm lucky because I found the perfect job early, without studying.

Study needs to be in the right form here, oftentimes after a proposition like without, the following verb will be appended with the suffix -ing

Oops, I forget to say what I'm gdoing :

I'm have been a tattoo artist since 2019.

The verb "to be" needs to be in the correct tense here, which is perfect tense ("have been").

When I was younger, I wanted to have a job who mix Art, Therapy and Socialthat was social and mixed art and therapy.

Mix needs to be in the correct tense, also social cannot be used in this context as it is not a noun, rather an adjective.

I thought about "Art-therapist", but I needed to become a "Psychologist" and after a "Art-therapist".

And I hadschool was a little trauma with schooltic, so, I don't want to havestudy for a long studytime.

While you can have a singular trauma, it's more common to describe the whole experience as traumatic.

In this context, study is a verb and is not something you can have.

(Now, I'm a little bit sad about this, because I love to learn/learning and I verreally wanted to discover more things with others passionnate people.

Learn either needs to be in its natural form or conjugated.

While "very" is a word that can be used to underline your point, it is not usable for verbs, which in this case is "wanted".

I tryied again with study last year, in an animation's school, but the gap in mentality gap between the others students and meI was so big.

Past tense.

"A" before a vowel becomes "an"

A lot of them wasere here just for fun.

Still past tense.

They used IAI for create art, they had zero motivation and zero respect for the teachers.

In English it is AI (artificial intelligence)

So, I stopped taking courses and,

Course is a noun, so something you take in English.

Actually, I learn alone.).

It's grammatically correct but could with more depth. "Actually, I learn best alone"

When I was 18 years old, I madedid my first tattoo on meyself.

This one is a hard one! But tattoos are something you do, not make, in this context.

And it was a revelation.

Great word!

But also therapy, because tattoos help people love theire bodies, and sometimes, it helps to keep important moments on us.

This one is also really hard, but try to take a look at the differences between "there" and "their".

It was a looooong way to become a tattoo artist, to foundind a good "master" who wants to help me.

If you put "to" in front of a verb, put it in its infinitive form. Want needs to be conjugated.

I'm lucky because I found the perfect job early, without studyneeding to go to college.

I think you mean study as going to school. Those are not interchangeable in English.

Oops, I forgeot to say what I'm gdoing :

I'm have been a tattoo artist since 2019.

When I was younger, I wanted to have a job whoich mixes Art, Therapy and Socialpeople.

But, in France, we don't have a lot of choices.

I thought about "Art-therapist", but I needed to become "Psychologist" and afterbefore "Art-therapist".

And I had a little trauma withat school, so, I don't want to have long studyto go to school for a long time.

(Now, I'm little bit sad about this, because I love learning and I verreally wanted to discover more things with others passionnate people.

I tryied again with studyto start school last year, in an animation's school, but the mentality gap between others students and me was so big.

A lot of them was ere there just for fun.

They used IA forAI to create art, they had zero motivation and zero respect for teachers.

It's AI in English because it's called Artificial Intelligence.

Actually, I learnstudied alone.).

Here is where you would use study

When I was 18 years old, I made my first tattoo on meyself.

But also therapy, because tattoos help people love theire bodies, and sometimes, it helps to keep important moment ons for us.

It's a social job too, because it's an exchange between the professional and the customer.

It was a looooong way to become a tattoo artist, to foundind a good "master" who wanted to help me.

I'm lucky because I found the perfect job early, without studying.

You can say “without studying” or “without having to study”

Oops, I forgeot to say what I'm gdoing :

“Forget” should be past tense and “going” makes more sense if you use “doing” since you are talking about what job you are doing

I'm have been a tattoo artist since 2019.

“I’m a tattoo artists” works but because you mention what year you became a tattoo artist, we use the past tense “I have been a tattoo artist”

When I was younger, I wanted to have a job whothat mixes Art, Therapy and Social.

I thought about "Art-therapist", but I needed to become a "Psychologist" and after "Art-therapifirst".

This is an easier way to say you need to become a Psychologist before becoming an Art Therapist.

And I had a little trauma with school, so, I don'idn’t want to have long studyspend a long time in school.

Using “didn’t” instead of “don’t” keeps the sentence in the past tense.

(Now, I'm a little bit sad about this, because I love to learn and I verreally wanted to discover more things with others passionnate people.

I tryied again with studying last year, in an animation's school, but the mentality gap between others students and me was so big.

Because you are talking about last year, we use the past tense “tried”

A lot of them was ere there just for fun.

They used IA forAI to create art, they had zero motivation and zero respect for teachers.

Actualynow, I learn alone.).

And I'm proud of meyself.
