Pushing one to the limits

The last two weeks of my orientation classes has taught me a hell lot of things. I have never been this busy in my life, nor did I ever imagine in my wildest dream that I would be slogging for 17-18 hours, and the best part even on Sundays, while the rest of the world is having a lazy day I am running around to give presentation and attend classes :-)
Well life for the past two weeks has been tough, but the experience I had would be cherished always and has taught me lessons which I would not have had otherwise. The most important lesson it taught me is that I realized that if I want I can achieve anything but I just have to make an effort to do push myself beyond my usual limits.
All through the past two weeks I have been pushing myself to the limits. When my orientation period started on 16th June 2008, I was expected to follow a routine which seemed like an impossible task to achieve, and was not quite sure of how I was going to adjust and perform in such a competitive environment. Today exactly 14 days into my orientation ,I have realized that with little time management , one can achieve miracles. During my graduation days I attended classes for around hardly 7 hours, moreover weekends were off and still I always complaint about not having time, I always wanted to do so many things , but as usual I was always short of time .
Now I realize what a fool I had been I had so much of free time then and had I utilized that then, I would have a completely different person now with a lot of assets, but I wasted all the valuable time I had. Now that I have realized this I hope I make the most of my time.
The problem with students like me is that we don't push ourselves to the limits, now I am sure many of us would say that “who says I don't, I do push myself o the limits”, but the fact is many of us are not aware of what this”limit” actually is, for e.g.:As I have already said that during my graduation days I used to work hardly for 7 hours, and I had thought that was my limit, as a result I never tried pushing myself to the actual limit. But now I have realized the my true potential is much more than I had thought, and sill I believe I can improve upon my efficiency because I feel I am doing he same mistake again, I am stuck wit the same thought - “ I cannot work more”. Each day of our life has 24 hours, and that's a LOT of time, but we do not realize it,and end up being frustrated and winning about not having enough time to do what we want to, so people just push yourself to your limits everyday and you would find that we actually have a lot more time than we actually need.
