It's useful and necessary to discuss learning habits. The good learning habits can make you learning something more rapidly and more efficacity more others. and in my opinion, the best good learning habit is insist. For exemple, someone learn 30 mins of English everyday. So he'll spend 15 hours in English for a month. And other one spend 3 hours in the first week of month, then the rest of the month he go to enjoy something he like. In the end, you think which one will be better in English? I think it will be the first person. Because the second person learned too much in the first week , I don't think he can control all the think that he have learned, the rest of the month he will forget all the think that he have learned. I have that idee, because I have try by mysel. In the fact ,I have a experience of this two case but how to be insist to do something ? I suggest that to write the planning, to try control you spare time , but also give youself to relax. And don't forget one thing that you don't have to do is learn too much in a short time.
