could you help me correcting this text? Thank you very much!

First of all, I’m interested in being part of the Guildhall School of Music and Drama because their goals overlap with many of my career goals. I would like to become a guitar teacher, I know how important it is introducing to introduce an instrument in a good way well for the beginners, and reading about this conservatoire, I feel a high level of implication of they have superb the professors at all levels, mixed with a lot of combined with excellent resources and opportunities. available. I love my instrument, but above all, I love all kinds of creating music, ( Do you mean you love composing all kinds of music, or do you mean creating all kinds of music by playing an instrument?)so I also value active teaching about many music styles that will make me able to play concerts without technique or musical genre limitations the limitations of technique or musical genre.
On the other hand, I appreciate being involved in other activities, like improving my language skills and reading or studying about different subjects and taking as much advantage as possible of any opportunity that a city like London could bring to me.
Summing up, what this center offers to me is exactly what I need to broaden my horizons and musical background , having the flexibility to explore other subjects, all with the purpose of becoming a good interpreter with the ability to express love (to) of music , and an experienced teacher with a lot to convey (offer).

I hope this helps. It is a complex piece of writting, and I may not have expressed exactly what you wanted to say. I studied in London. It is a great place for students. (But that was a long time ago!)

First notebook entry: I try to learn English

I am learning English because is more important for my job. I'm a teacher. My native language is Spanish, I live in Sevilla in Spain, in a town called "Osuna".

Very good. I usually live in Wales, in a village called "Hirwaun". Now I am in Spain, in Murcia, near Mazarron.

First notebook entry: Introducing myself

I am a 35 year-old girl from Spain. So, my native language is Spanish. I've been learning English for years but the most difficult thing while you are learning a language is to have the possibility of using it daily and not to forgot it. I would like to improve the fluency

I enjoy travelling, painting, lying in the sun but I don't have enough time for all of these things...

This is very good. There are no mistakes but I can improve the fluency a little.

....learning a language is the chance to use it daily....

..... improve my fluency.

I have been trying to write a little in Spanish every day. While I am in Spain I do not have the internet at home, and it is not so convenient in the internet cafe. I will try to look at "italki" when I can. I will look out for your postings. Hasta luego!

I found these two as well, I thought you would like them.

If you talk about silver lining you are talking about something positive that comes out of a sad or unpleasant situation.
