Restart learn English (Re-starting to learn English)

I got interested in English three years ago, but my English studying was interrupted by (for) various reasons. I (recently) decided to restart learning English, i (and) plan to go to an English training institution (English language school). But I have (want?) to improve my English to a normal (better / higher) level before entering the training class. So I have set a goal for myself,; the first week, pick up more than two hundreds words per day, the following weeks, memorize one hundred words per day. So (Such that,) a month later, I should know about four thousands words. I think vocabulary is the base of learning English.
last night, i didn't go to bed until 3 am, because i hadn't finished my learning task. although it's (I'm) tired, i feel happy.
I have never been to an English native speaking country (a country where English is the main language), so the way I speak English must be incorrect. That's why i registered on italki and wrote the (this) composition.
I believe that all the efforts would will get rewards. Nothing is difficult to a willing heart!

Oops, the title should be Restart to learn English
