wax on,wax off......

Yesterday in the lecture,the prof,noticing the number of students sleeping in the class,made an interesting comparison.He compared our training to the "wax on wax off" training Mr. Miyagi,a martial arts master,gives to his pupil in the movie "the Karate kid",in which he makes his pupil wax his car everyday in a particular manner.The kid feels so frustrated and cheated,all his fascination about karate is gone,he thinks "Why the hell am i doing this?".But in the end,this and such other modes of training make him the champion and it is only then that he realises the value of it all.
Is it similar to what we have been doing?Throughout school and now college,this question "Why the hell am i doing this?" comes so often to my mind,all of it seems so boring and worthless(well,mostly),for me it is just waxing a car,nothing more,but at a deeper level,maybe all this prepares me for what i am supposed to do in life.And why only courses,doesn't it apply toh almost everything in life,most of the things i do seem so worthless,boring,of no use at all,but each one of such "useless" things changes something inside me,each time i grow bit by bit.And now that i come to think of it,look at the degree of subconciousness of it all,i myself never come to know of me changing,i can't tell how or when,i cant say"look,i changed so much on this day,in this particlar week,month or year",i seemingly stay the same everyday,and yet,i somehow manage to change over and over again,strange!(strikingly similar to the concept of integration,funny how math corelates with so many things in life)
