But first of all, here is the number one piece of advice:
Whatever you do to practise your English should be interesting and fun - for you.
Watch TV shows you like, read articles you are interested in. Listen to songs you like. DO NOT kill yourself trying to understand the BBC news if you would prefer to watch Friends.
The next most important piece of advice is:
Don't try to understand everything. Relax, let the words flow over you. If you're reading, look up only the really important words. If you're listening or watching, it doesn't matter if you don't understand. Your ear is unconsciously attuning to the language.
Practising your English in your free time should be enjoyable.
Fun = you're more likely to continue and do it often.
Boring = you're more likely to give up and then feel guilty.
Just do something in English. Even if it's only for 2 minutes.
