How Do You Study?

I'm currently juggling schoolwork, with newly introduced 'adult-stuff' (find a job, car, etc). I plan on leaving to stay in Japan for three months starting next year, and I want to at least sear the basics of Japanese into my brain before going. 

I'm not good at keeping a schedule, though! So, I was wondering if I could pick up some study habits from fellow italkers. Thank you!
