I think that the biggest investment risk I've taken in my life was when I decided to go back to school.
I had just graduated with a degree in business, and I knew I wanted to get my master's. My family and friends were not so thrilled about the idea—they thought it would be a waste of time and money. But I knew if I didn't do it now, then when would be the right time? And so, despite their protests, I went back to school.
