My strengths and weaknesses in English

It is very difficult for me to say which one is my strongest and which one is my weakest ability in English. All of them are difficult for me. But if I had to identify one of them as the weakest and the most difficult for me,  I would say that speaking is the language ability in which I have more difficulty in English. I am able to understand everything when I read and when I hear other people speaking English. And writing is not specially difficult for me. I read and correct a hundred times everything I write, but I can express myself accuratley by writing. However many times I do not get to express what I want to say when speaking. Many times I tend to get confused and I help myself with movements and expressions.  This happens to me because sometimes I still try to translate from Spanish to English when speaking. There are some expressions that we have in Spanish that don't exist in English, but sometimes when I speak English I try to find the exact words that are used in Spanish and that is when I get confused and start to get nervious and stutter. I have realized that English is much simpler than Spanish regarding structures and grammar.
The best way to improve this weakness would be to be always aware that there are many different ways to express the same idea and that there is no need to use exactly the same words that would be used in Spanish. I think though, that I have improved my speaking a lot by practicing, so I have to keep on speaking and practicing to improve this ability.
