Feeling down

There are days when all the hard work done is wiped out because of one mistake. Today seems one of those days. I have been working on a report over the last couple of days and finally after 2-3 reviews released the same, only to find out there were a couple of mistakes in it. The nature of mistakes does not really count as a mistake is a mistake no matter how small or large. Sucks really because all the effort is now wasted and what stands out are mistakes. I have already taken measures to ensure that the same thing does not happen again but the damage has been done. Oh well.. cant do much about it now.
