There really is no "specially effective" way or a short cut. You need to put in the hard work over a long long time just like anything in life. As for how to go about it, my belief is that reading is the basis for everything. Read (and listen) mostly, noting pronunciations, looking up grammar as necessary. The reason reading is important is because that's the best way to expand your vocabulary. Reading (and listening) attentively is always the most efficient way to get to fluency fastest. Find good texts that interest you, with audio as well if possible, then read, read, and read. Once you get to point where you can comfortable read newspapers and dense books, listening, writing, and speaking all eventually follow. That is my tip coming from experience.
