Do you have a good level of English?

The point of speaking English to me is I am from England.

I don't understand tenses, and I have difficulties writing and read long and complex sentence structures.
English is a world language, everywhere you go you'll encounter English speaking people.

Sometimes I feel I mess up the structure of a sentence (wrongly place phrases ahead of others), but then I often feel the same when I am writing in my native language, so it is fair enough lol

Yes, and I don't think it's that complicated. It's the only language I speak.

It’s probably spoken in every country so you'll have an easier time getting by.

It's not as useful in London as it used to be :)

Tenses make me tense.
