If I were a business professor and you were my student, today's lesson might sound like this: In the "real" world, it's better to have loved and lost, tried and failed, dreamed and missed, than to sit out your turn in fear. Because the loss, the failure, and the miss, however painful, are merely temporary market adjustments, soon forgotten. Whereas the love, the adventure, and the dream are like investments that, for the rest of your life and beyond, never stop paying dividends.
