1. Buy a “basic” training course for the beginners to learn basic grammar – the only expense
2. Watch TV – on Internet are plenty TVs in almost all languages for free
3. Play games – chat in that game, and use TeamSpeak to listen conversation, be active
4. Read books – for beginning the fairy story for kids
5. Watch movies with original sound and subtitles
6. Create blog and write your ideas in your “new” language . Peoples will call you  “the hun”, but you will at least practice
7. Use your dictionary (the best one is to have one in PC, and one book version) every-time you don’t know some word!!!
8. Use your new language every-time you will met some native speaker! Talk with him, chat with him, don’t care about your bad pronunciation. Without training is no progress!

BTW the most valuable languages are:

• English - whole Internet is on it, it’s the “Esperanto” of the 21th century
• Spanish - large population on the world speaking Spanish
• Chinese - China is the the new king (GB was in 19th century and USA in 20th century, right now is century of the China)
