Well, I don’t know how to start,. I am trying to write manylots of things, but I haven't got any ideas. Well, I don’t know how to start. I am trying to write lots of things, but I haven't got any ideas.

This is two separate sentences, so you need the full stop in between.

Well, I don’t know howwhere to start,. I am trying to write many things, but I haven't got any ideas. Well, I don’t know where to start. I am trying to write many things, but I haven't got any ideas.

Well, I don’t know how to start,. I a’m trying to write manya lot of things, but I haven't gotdon’t have any ideas. Well, I don’t know how to start. I’m trying to write a lot of things, but I don’t have any ideas.

You could add a full stop after the word ‘start’. And “a lot of things” sounds more natural than “many things.” We often use “a lot of” in casual conversation. Also, “don’t have any ideas” flows better and is more typical in everyday English than “haven’t got any ideas.

My first text inon this website. My first text on this website.

careful with distinguishing ‘on’ and ‘in’!

My first text inon this website My first text on this website

in/on prepositions are tricky, but in this case you're on a website so it is 'on (this)' instead on in!

My first text inon the website My first text on the website

We use “on” for websites, just like we say “on Facebook” or “on a page.” “In” would sound a little odd here.

I am going to read something and then after write a more interresting text afterwards. I am going to read something and then write a more interesting text afterwards.

You have to put “afterwards” at the end, instead of “after” in the middle

I am going to read something and then after write a more intertresting text. I am going to read something and then after write a more intetresting text.

I am going to read something and then after write a more interresting text. I am going to read something and then after write a more interesting text.

Sometimes English speakers say after -that- but ommitting it here also works just as well!

I am going to read something and then afterI will write a more interresting text. I am going to read something and then I will write a more interesting text.

I am going to’ll read something first, and then afterI’ll write a more interresting text. I’ll read something first, and then I’ll write a more interesting text.

I’ll” is a contraction that makes it sound more conversational. “Then after” is a bit redundant, so “and then” is enough to smoothly connect the ideas. It’s just more streamlined this way.

iI think this text is very simple i. If you can to improve it and makes it more natural, willthat would be amazing. I think this text is very simple. If you can improve it and make it more natural, that would be amazing.

Don’t forget the verb “is”! Also, we don’t use the infinitive after “can” - so it is can improve, not can to improve. Remember to include the subject of the sentence, “it”. When talking about something that might happen, we use “would” instead of “will”

iI think this text is very simple i. If you can to improve it and makes natural, will it sound more natural, that would be amazing. I think this text is very simple. If you can improve it and make it sound more natural, that would be amazing.

Your wish has been granted. Remember to use more verbs!

iI think this text is very simple if you can to improve it and makes it natural, it will/would be amazing. I think this text is very simple if you can improve it and make it natural, it will/would be amazing.

Remember your verbs and articles ! Instead of will, AKA future tense, I would use the conditional tense, "it would be amazing". "It will be amazing" still makes sense, but using the conditional here is a bit more natural!

iI think this text is very simple i. If you can to improve it and makes it natural, that will be amazing. I think this text is very simple. If you can improve it and make it natural, that will be amazing.

i I think this text is very simple, but if you can to improve it and makes natural, will it sound more natural, that would be amazing. I think this text is very simple, but if you can improve it and make it sound more natural, that would be amazing.

This sounds good, but using “if you can” instead of “if you can to” makes it grammatically correct. “That would be amazing” sounds more natural than saying “will be amazing,” because you’re imagining a possible situation, not a definite one. And the word “I” is always capitalised in English.
