Lack of motivation

This is just a problem I'm experience with all my studies, not just Japanese. For the last couple years I've been slacking off continuously and it really shows, what do you do when you're down in the slumps about your education?

I've been recommended award systems, programs like cold turkey to stop my pointless internet browsing, sleep more often and to chip away at my work load rather than trying to smash it all at once. I don't have the will power to keep up with it, it works for maybe two or three weeks and then it starts to fall apart. 

どうするの？！？！？！？

広東語を読めたい！！！ 私はオーストラリアで生まれたが。中国系がある。祖父は広東語や官話やベトナム語で話せる。でも私は英語と広東語だけ話せる。もう時々ホンコンから家族に喋ったら分かりにくい。だから子供の時に広東語で書いたり読んだり擦ること学びたかった。 It's pretty annoying being illiterate in a language, especially when your accent in Cantonese makes you sound like a bogun, (Bogun? Bogan?) and it would have been REALLY useful when I started to learn Japanese. What I've written in Japanese should /I hope says 'I was born in Australia, (contrast が particle not really sure how to explain) I have Chinese lineage. My grandpa can speak Cantonese, Mandarin, Vietnamese etc, but I can only speak English and Chinese. Sometimes when I talk to family from Hong Kong, it's difficult to understand. Therefore I wish when I was a child, I had learned to read and write in Cantonese. (This last sentence was really difficult for me because I wasn't sure what tense I would use and where.)
