but i never devote all my energy to it 
I just think I don’t like the idea to learn of learning English in the school because I’m think it is bored and I think I can learning English by myself! So I want to know which is the best ideas for of  learning Enlish more faster?

i think if you want to learn a language faster, sometimes we need a teacher to help us correct and improve grammar and speaking. 

Grammar and speaking are the most important parts in language learning,  And for the reading and listening, you could learn by yourself on the Internet.
