the first thing, i will never waste my time again, you know franklin said :"never leave that until tomorrow, which you can do today." i will do it as good as words of franklin.
the second, i will ask more questions which is a puzzle for me. because of these things can let me understand all of knowledge in book very well.
the third, i will do more execrises.for example, english, maths, chinese and so on.
to sum up, time is too improtant to let me get a good performance, so action is only one thing i can do! i will action more, less talking.
