I remember I built this exact same thing. I was bored at work and made a small counter of how much money I earned per second, and I enjoyed very much how the number was incrementing. I started gold plating the application, adding features, animations. Soon I was able to configure how much would I make pr day, how much remained of the day. How much remained of the week..<p>Then I started thinking about averages, and added in configuration to the timeline that would show approximately how far I had progressed until retirement, and then approximately estimated lifespan remaining.<p>I had it running for a day or so, and just by watching the time tick away made me realize something, I discovered something profound and important to me. The application disgusted me, and I deleted everything.<p>I don't want to be reminded, it depressed me. Today, I try to cease the moments, and enjoy every seconds. Even the bad things are good. Everything is precious and specially wonderful. I am fortunate to have a unique perspective and my life is easy.<p>Some things are better not to know, to think about or speculate about.
