I always think about how ways to improve my English.

I always think about ways to improve my English.

I tried different ways for to improve it. However, I felt the lack of something.

I tried (many / a few) different ways, but even though, I feel something's missing.

- Add "many" or "a few" to sound more fluent.

- Do not repeat (to improve it) you already mentioned it in your first sentence.

- I feel something's missing, is a better way to express I felt the lack of something.

I don't konow about but it is there.

Badly expressed, it's difficult to understand what you mean, so it's better to delete it.

I studied at university education in english, even so though my English is still bad.

I even studied at university in English, but my English hasn't improved. 

Note the changes I have made in order to sound more fluent.

My vocabulary has technical English words.

This sentence does not make sense. 

Another thing, I (need / want) to speak English with anyone.

In addition, I need to practice speaking English with someone.

- Moreover / In addition / Furthermore are all better words to use than another thing.

- You either use "need" or "want" .. not both ! 

- You need to "practice speaking" not just "to speak".

- "Someone" is used even if you don't mind "anyone".
