the first according to me is to never feel tired from inside. if somebody feels and thinks himself tired from in his own self then growth can't be achieved ever. to attain success, we have to work until we get our destiny. it is not necessary that your last destiny is realy or truely the last. that may be the beginning. so never get tired from inside. because inside courage or self is the one who only can take you to the destiny or so far.
sometimes these talks or saying words looks like words only, but only these words and you yourself can bring you to any position,designation or destiny where you want to be.
there are many ways also that is to seen from many ways. so changing thoughts about the problem can also be a way but work for that is needed from our side.
