Start!

If you don't start, you'll never finish.

The longer you put it off, the more likely you are to give up.  So start. Now.

Find an English class.

Find some English learning software or books.

Join an English learning forum.

Begin learning the English alphabet (ABC) and numbers (123).

Learn the vocabulary for your hobbies or interests.

I am a great fan of the JDI methodology - Just do it.  Do something. Do anything.

And once you've started - don't stop.

So, the next time someone says to me "I want to learn English", I am going to reply, "Get on with it then".
