SinceFor the past 3 months, I amhave been very motivated to improve my English.

I think it's very important for my future beingto be fluent in English, and I also would love to easily understand easily everything said in English.

I made just a few changes here to be concise. We don't need to refer to your future because it's assumed that you are referencing the future since it's something you're working toward. We would also put the adverb "easily" before the verb "understand" - so "easily understand" instead of "understand easily". Just a bit more natural.

I think it will be difficult but I have to challenge me and asyself and since I am motivated, I think it's possible.

Here, you're referring to yourself as a direct object, so you would be "myself" instead of "me". We would say "since I am motivated" instead of "as I am motivated.

In order to improve all my English skills, I made a program that I do everyday.

For improving my oral comprehension, I watch a yYoutTube vlog in English with stubtitles in case I don't understand everything.

Just a few spelling errors here. Also, any time there is a proper noun, we would capitalize it. Here, you reference YouTube, so you capitalize the "y" and the "t", as that is the proper title for the website.

I also write some words and expression I put in Anki in order to learn them when I have the time for.

Moreover, I do the shadowing technichque, which consists tof repeat an English nativeing words that native English speaker wordss use.

I do that for 15 minutes and it's very helpfull for the oral expression, particularly with the fluency and the pronounciation.

Just spelling errors!

For improving my oral communication, I add 10 minutes of speaking with gGliglish, an AI.

I'm not sure what Gliglish is, but considering that it's probably an app or a website, you would capitalize it, as it is a proper noun.

For the grammar, I learn everyday a new lesson, and a new grammar's rule in aeveryday on the website: English Breaitish Council.

To conclude, IFinally, I love to listen to music in English I love to, and I try to learn the lyrics.

"Finally" is a bit more natural here. "To conclude" would make more sense if you were recapping ideas that you previously expressed. You'd use "finally" here because it's the last thing in the series of activities that you do.

To concludeFinally, I listen to music in English that I love to and I try to learn the lyrics.

"To conclude" means you are about to summarize all of the points you made thus far in your text. But you did not mention music before; it is rather a last item on your list.

Thanks for reading, I hope you enjoyed reading my text!

Since we are now at the end, past tense "enjoyed"
