I would recommend you to find a text with an audio and do the following steps:
1.) Translate the text (word by word) and write the translation under every word you don't understand "at first sight".
2.) Listen to the text while you're reading the original text and as you arrive to the words you don't understood, switch down to the translation (you've made) and read the words you don't now already in your NL. Do this several times, as long as you're familiar with the new words.
3.) Now you should be able to listen to the audio (without reading) and understand all the words.
4.) This is the point where the "time saver" comes in: Now store your language stuff away and continue listening to the audio. Set the volume of your computer/mobile phone to a very low level so that you just can hear all the words. Now you can do other things (like cooking, cleaning your flat, hiking etc.) and you can train yourself not to concentrate at all on your audio (it's possible, I made it too) what will allow you to do more "advanced" tasks while listening (studying, reading, homework, writing).
The good thing about this method is, that you don't have to practice but instead you delegate the practicing to your brain (this is what happens when listening unconsciously to your text). You will sometimes "detect" a word or two and then return to your task you're concentrating on - this is normal ...
Me myself I learned a lot with this "time saving method" (called the "method of Birkenbihl", by the way) and I'm now even learning complex latin texts with this method - it works like magic...
