How can I let it all go?

I ve been, for the past couple of weeks, recreating my resume, my marketing postion. Its the periodic resurrection we humans take upon ourselves.
I use the word generate instead of revive my "dossier-at-a-glance" because this time I am cutting myself from the ties and the world of a student life and breaking [hardly] into the realm of the working class, the first step into the bourgeois life. Surprisingly, and somehow embarassingly I never realised this metamorphosis will involve more than stringing some words together- nicely! A Lot More!!

With the formal education era safely [more surely] behind me, and a fistful of solid [read relavant for once!] work experience under my belt, it was time to sell my self differently! After all the research on "what your resume should say about you, and how" I fianlly got down to writing it and with excruciating pain at that.

It struck me forcefully that having come as far as I have this new resume will involve cutting off more than a hefty chunk of the earlier contents. And this content that I refer to mean actuall achievements of mine over the years. e.g. to score highest marks in economics in the entire class and get formal recognition for it was an achievement for me. Just because it happened in the first, and concurrent years too, of my bachelors doesn't make it any less precious for me. B-u-t since this occured in the final few years of the last millennia [well, put that way!!] I have to now cut it off??
There are a lot of such things to be left behind now that I must look to the future. But I am perturbed by it all. I cannot forget -easily- the journey through the various degrees and the various things I indulged in [i mean academically, although yes, there were a few indulgences of the not-to-mention kind too]. Each award/certificate/medal ...things that made me proud when I looked at my so called student resume, sentences on paper that filled my heart with warmth and pride....all meant and mean so much to me even now. All those had come my way as a result of sincere and consistent effort. They were not fluke or easy [I am not the born to achieve types, hard work was always my magic lamp]. To think that all of that doesnt matter any more, that it 'has no place' anymore fills me with disquiet.

If the past doesn't matter after a while, then why put much efforts in the present for that will turn itself to past soon, will it not?
