Mistakes Happen Even if you’re an Investment Guru The Need to be Included Leads to Many Things

Never Let Human Emotions Determine Investing Practices

Human beings are subject to wild swings in their levels of fear, risk tolerance and greed. That won’t change.

The reason Shakespeare is so relevant still today is that his plays were all about human nature, and human nature never changes.
