a self-righteous mistake

    When I think of the problem that is so easily sovled,but I have a long and devious way of exploring the method.what make me spend so long time?how can I work out it next time?

    Recall the question that I have run into today,I discovery I get some anticipation in my mind since I get the problem.It made me doutful.When I found some approach to it,But I found that method lack some convience,So I always thought it hard,and keep to do it lastly.So I have been finding another method.But I woundn't.

    Now I sum some point.Firstly,when you can find some answers in some place,don't try to think of it yourself,but to work it out by those method.because other people like you have come across it,they have got it,and wrote down it.

     Secondly,when go nearly to answers,you may find hard to go on.then you need to think of it another way!don't think there is only one way to figure out it.
