Today i want to write my feeling as informal essay which i experienced recently in here .i want to talk about habit.habit,i did not pay attention to it before,and didno't think  the question that  habit is  important or not for a man .on that time i thought habit could not play a important role in our life.i started to consider habit from the time when i read some articles writed by DioEnglish friends.now i found that habit is too important and one of the key factor of one's success.i think habit is very powerful whether it is good or bad.of course ,all of us look forward to it is good .no one want to be bad here.habit means offten,go ahead ,insist on.....which we want .learning need long term accumulation ,long term accumulation need long time insiting on .if we take a learning method as habit ,it would be useful for us ,i think it is realy called as grasping compeletly.learning should be active but not passive. bad habit is dangerous !i very afraid it ,it can destory one's life ,bad habits are hard to be modified,it maybe with them all our life.so we should more attention to our habits ,from a good habit to keep away from bad habit!
