Before Mint.com, I was a long-time user of 'Microsoft Money' and Intuit's 'Quicken.' Both were powerful tools, loaded with features and functionality around taxes, investment, budgeting - too feature-laden, in fact. They took hours to set up, forever to learn, and an hour a week to maintain.

The original idea before Mint was a life and goal planning system I called Carpe Viva. The idea was that all of life's goals, from buying a house, getting an MBA, or learning Spanish could be quantified in both time and money.

Carefully calculate the potential size of your market to make sure you can grow. Before starting Mint, I knew that there were about 20 million people who had purchased 'Quicken' or 'Microsoft Money' over the years, and 80 million people using online banking in the U.S. alone.

I always knew I wanted to be a technologist, so I went to Duke and got a degree in computer science and electrical engineering. Really, I thought my goal in life was to be an inventor, a problem solver, so I thought I needed a Ph.D. to be good at inventions, but it turns out that you don't.

I always feel like 'as long as I'm doin' what I love to do, the money's naturally gonna come.' When you start thinkin' business and you start thinkin' 'What's hot? What's the wave? Who is hot? Let's get at that person,' it becomes a point where you're tryin' to strategize to make money. And that's always a gamble.

It's a great story for us whenever an entrepreneur makes a crazy amount of money and we get to tell the world about it. For the entrepreneur? Not so much. Hitherto unknown relatives, entrepreneurs seeking angel investments, money managers and supposed baby-mamas all come out of the woodwork with dollar signs in their eyes.

Profit, wealth creation, competition - these are not dirty words but the lifeblood of a dynamic economy.

The first thing I heard when I got in the business - not from my mentor - was, 'Bulls make money, bears make money, and pigs get slaughtered.' I'm here to tell you I was a pig. And I strongly believe the only way to make long-term returns in our business that are superior is by being a pig.
