Although most students would be unhappy if they found that they had failed an advanced math course ,they have actually learned a great deal about themselves.They know they should not become engineers or physical scientists and that they would not be bood at accounting work .So failing can help a student to lead a much happier life if he or she draws the right conclusion from the failing.They may then decide on their goal and choose the kind of work they would like to do.
It is impossible to decide wherther or not you like something until you have tried it .If you decide that you would lide to play the violin ,you need ti take more than one lesson before you cna know whether you have any interest or ability.
It's not enough to want to be a great violinist .You also have to like the hard and long training before you become one .If you would enjoy being a great violinist but hate the work,forget it .
It's a good plan to try as many ideas as possible when you are still young.And then you will come to a wise decision.
