Most startups, especially small enterprises, are immensely personal endeavors. Entrepreneurs feel the tremendous weight of every decision. While the right moves at the very least bring about one more day in business, a single wrong move can spell disaster for the people involved.

And, yet, startups are treated by outsiders, especially the financial press, politicians, and critics, as paths to equitable returns, engines of innovation, or symbols of corporate greed. When interviewing founders, one should remember what they, as human beings, have sacrificed, or will sacrifice, for not just success but their dreams.

Here are some of the best questions to ask entrepeneurs…

• How has the startup impacted your family, social life, or relationships? Have you become more cognizant of the quality of life needs of your employees?
• If you sold your company today, what would be the tone of that conversation? What would you want to gain? What would you want to avoid losing?
• Many entrepreneurs are forced to leave their companies. How would you feel if you found yourself in that situation? What would you do?

But the most revealing question could be quite a bit simpler: "How has your day been?"

I have asked these questions in my interviews. One of my favorite answers was given by Ken Williams, cofounder of Sierra On-Line. The answer was unexpected, to say the least.

Williams: […] It was also a problem for our family. There were no private schools, and the public school in Oakhurst, where we were based, was rated among the lowest in California. None of our children's peer group seemed interested in college. We had moved to Yosemite in 1980, but by 2003, it was clearly time to leave if we wanted the company to succeed—as well as our family!

Ramsay: With a family of your own, were you more cognizant of the more human needs of your employees? Did this influence how you thought about "the Sierra way"?

Williams: The sad truth is that I was not much influenced by family. Both Roberta and I are workaholics. If I'm awake, I am generally at my computer. I have been retired for 13 years, but I still try to write some code every day.

My philosophy of business has always been that business is war. You need to decide if you want to win or lose, but there isn't an option to just show up. To beat the other guy, you need to get there sooner, hire better people, work harder, start earlier, focus on every detail, and have all of the luck you can get. I can't remember ever taking my sons to a baseball game. I never coached any team for the kids or went to a PTA meeting. I prided myself on trying to go weeks without small talk with my secretary.

We were young, and wild parties did occur, but these were exceptions. At Sierra, my "business is war" attitude generally prevailed, and anyone who needed family time didn’t understand the problem.

As an aside, there is truth in retirement. The most self-honest answers come from those who had time and distance to reflect. Ken Williams has been retired for more than 20 years, exposed to the elements on his yacht. Working founders, however, are still living and breathing "in the moment," unaware of their blind spots and charging toward what could be only the illusion of destiny.
