Spend your time on things that interest you. If you like then buy an English-language cookbook or find recipes on the net and practise following the recipes. You'll soon know if you have made a mistake!
Keep something English on you (book, newspaper or magazine, cd or cassette, set of flashcards) all day and every day, you never know when you might have 5 spare minutes.
If you are too tired to actively practice just relax and listen to a story in English, an English pop song or talk radio station.
Get onto Google Plus, Skype, other social networks, or be really adventurous and start socialising in Virtual Worlds.
Start networking with native speakers / teachers and other learners.
Don't restrict yourself to seeking out native speakers. Think about it, the likelihood of needing to speak English with non-native speakers is statistically much higher.
