When I pick up a new language I always like to try and make simple games or projects on my own. They don't have to be real complicated or even serve a real purpose. It should be just big enough so you get a feel for the language. If you find yourself struggling with something on your project, that can give you a starting point for more formal training like @cecilphillip suggested. I am a big fan of PluralSight and use it all the time.
