The pain is knowing that you have to trick yourself into believing that there is still hope. Yes, you thought that your current approach was promising, more promising than all of the others you have tried. Yes, every test along the way showed results that were leaps and bounds better than the predecessor. But alas, one final test, and the goal remains just out of reach. And so you are back to brainstorming at the chalkboard. Not to worry. This time around you’re more experienced, more patient; you’ll cook up something even stronger.
