Today I agreed to work on a very complex spreadsheet as a consultant and I have been sitting at this computer for over 12 hours. I’m almost finished but let me tell you – my legs are stiff and cramped and my head hurts like there are 20 little elves inside with jackhammers going into my skull. A person can only take so much aspirin and coffee. I think I need to just stop for the night and finish this up in the morning. But making these numbers work out and make sense is such a thrill – it is hard to stop when I’m so close to finished!
