My difficulty with verb ''To take''

I don't know how to use it well enough,
It appears to have several meanings. I get very lost and confused! :(

Is it polite?

“For safety reasons, we couldn't borrow an extension cable, therefore a colleague  of mine recommneded the nearest store. It was truly a gesture of generosity,

We really do value about you as our guest and we genuinely want you to know that we didn't intend to be discourteous.”

Learning english

I have been studying English for months and the most difficult thing for me is listening, I think it is very common when a person learn another language mainly because the accent or tone is particularly different in each country.

I was thinking that it would be a good idea to travel to another country but unfortunately, it isn't easy at least for me so I was wondering if it's possible work and travel. I consider that it could be the best option for me, I from Mexico and I studied computer science, I don't have problems if I would have to work in others activities like waiter, cashier or administrator things because my target is improve my listening skills.

Now I'm looking for any opportunity on the internet. If someone knows of any program in your country or something similar, I would like to know about it. I would be grateful for your help.
