Dailly learns 5-10 new English words.

Start by learning practical vocabulary.  Learn words that are actually important to you at work, at home and out and about. 

Use stick it notes and labels things around your home.
Use self-study vocabulary books, these should include a good dictionary and a thesaurus.
Expose yourself to as much English as possible by reading, watching the TV, films or the news and listening to the radio or music.
Read an English magazine. If you can afford it take out a subscription to a magazine or newspaper.
Do online exercises. Keep a note of how you did and go back in a few weeks/months to see how you have improved.
Try to memorise whole sentences, not just individual words. When you have learnt a word, write about it in context.
Create or play word games. Scrabble, Crossword Puzzles, Hangman, and Dingthings are all great ways to play with words.
When you know you need to learn a particular word list for a test, start using the words immediately, use them in context and frequently. See if anyone is talking about those words online and comment on people's blogs or pages in Facebook, or on Google Plus.
Review, revise, review.  These are my 3 rs.  Review your word lists.  Revise the ones you keep getting stuck on.  Review the list ... ad infinitum.

No one said it was going to be easy, but unless you are studying to become an  Aerospace  engineer, it's not rocket science.
