David lost half his retirement savings on a single tech stock crash. He says the mistake was pure impulsivity. "It looked like a fast profit. If only I had researched the company more thoroughly before putting in so much capital." He is extremely anxious now, constantly monitoring the markets. "It’s an addiction," he admits. I wish I would stop checking the stock market every five minutes! It's consuming my life." He also regrets trusting the online tipster who sold him the idea. If only I hadn't listened to that anonymous tipster. Now he is stuck working an extra decade. I wish I wasn't facing another ten years of work.
