Maximize Upside or Minimize Downside

I know some people that focus on minimizing the potential downside of an initiative, project, idea, etc. It isn’t that they have negative personalities, it’s that they worry about what could go wrong as part of their core being. They can’t turn it off, no matter how hard they try.

I know some people that focus on maximizing the potential upside of an initiative, project, idea, etc. It isn’t that they are ignorant of the challenges, it’s that they focus on the potential and inherently have blinders on to all the nuances. They often hate the details.

The world needs all types of people. Startups often do well having both types of people on the co-founding team, with a healthy give and take relationship. Someone needs to think big and maximize the upside while someone else needs to counterbalance and look for ways to minimize the downside. Dreamers and worriers go well together.

What else? What are your thoughts on maximizing the upside and minimizing the downside?
